The XC9223/XC9224 series are synchronous step-down DC/DC converters with a 0.21Ω (TYP.) P-channel driver transistor and a synchronous 0.23Ω (TYP.) N-channel switching transistor built-in.
A highly efficient and stable current can be supplied up to 1.0A by reducing ON resistance of the built-in transistor.
With a high switching frequency of 1.0MHz or 2.0MHz, a small inductor is selectable; therefore, the XC9223/XC9224 series are ideally suited to applications with height limitation such as HDD or space-savinga applications.
Current limit value can be chosen either 1.2A (MIN.) when the LIM pin is high level, or 0.6A (MIN.) when the LIM pin is low level for using the power supply which current limit value differs such as USB or AC adapter.
With the MODE/SYNC pin, the XC9223/XC9224 series provide mode selection of the fixed PWM control or automatically switching current limit PFM/PWM control.
As for preventing unwanted switching noise, the XC9223/XC9224 series can be synchronized with an external clock signal within the range of ± 25% toward an internal clock signal via the MODE/SYNC pin.
For protection against heat damage of the ICs, the XC9223/XC9224 series build in three protection functions: integral latch protection, thermal shutdown, and short-circuit protection.
With the built-in U.V.L.O. (Under Voltage Lock Out) function, the internal P-channel driver transistor is forced OFF when input voltage becomes 1.8V or lower.
The XC9223B/XC9224B series’ detector function monitors the discretional voltage by external resistors.

General Description
The XC6204 series are highly precise, low noise, positive voltage LDO regulators manufactured using CMOS processes. The series achieves high ripple rejection and low dropout and consists of a standard voltage source, an error correction, current limiter and a phase compensation circuit plus a driver transistor.
Output voltage is selectable in 50mV increments within a range of 1.8V ~ 6.0V.
The series is also compatible with low ESR ceramic capacitors which give added output stability. This stability can be maintained even during load fluctuations due to the excellent transient response of the series.
The current limiter's foldback circuit also operates as a short protect for the output current limiter and the output pin.
The CE function enables the output to be turned off, resulting in greatly reduced
power consumption.

Maximum Output Current : 150mA
Dropout Voltage : 200mV (IOUT = 100mA)
Maximum Operating Voltage : 10V
Output Voltage Range : 1.8V ~ 6.0V in 50mV increments

 The XC6214 series are highly precise, low noise, high current, positive voltage low dropout regulators. They are fabricated using Torex’s CMOS process. The series features a voltage
reference, an error amplifier, a current limiter, a thermal protection circuit, and a phase compensation circuit plus a driver transistor.
 The output voltage is selectable in 100mV increments within the range of 1.5V to 5.0V. (Output voltage 1.5V, 1.8V, 2.5V, 3.0V and 3.3V are standard products. Other than these voltages are available as semi-custom products.)
The series is also compatible with low ESR ceramic capacitors, which give added output stability. This stability can be maintained even during load fluctuations due to the excellent
transient response of the series.

 The over current protection circuit and the thermal shutdown circuit are built in. The over current protection circuit will operate when the output current reaches current limit level.
The thermal shutdown circuit will operate when the junction temperature reaches temperature limit level.

The XC6101~XC6107, XC6111~XC6117 series are groups of high-precision, low current consumption voltage detectors with manual reset input function and watchdog functions incorporating CMOS process technology. The series consist of a reference voltage source, delay circuit, comparator, and output driver. With the built-in delay circuit, the XC6101 ~ XC6107, XC6111 ~ XC6117 series’ ICs do not require any external components to output signals with release delay time.

 Moreover, with the manual reset function, reset can be asserted at any time. The ICs produce two types of output; VDFL (low when detected) and VDFH (high when detected).
With the XC6101 ~ XC6105, XC6111 ~ XC6115 series’ ICs, the WD pin can be left open if the watchdog function is not used.
 Whenever the watchdog pin is opened, the internal counter clears before the watchdog timeout occurs. Since the manual reset pin is internally pulled up to the VIN pin voltage level, the ICs can be used with the manual reset pin left unconnected if the pin is unused.

 The detect voltages are internally fixed 1.6V ~ 5.0V in increments of 100mV, using laser trimming technology. Six watchdog timeout period settings are available in a range from 6.25msec to 1.6sec. Seven release delay time 1 are available in a range from 3.13msec to 1.6sec.

* Detect Voltage Range : 1.6V ~ 5.0V, +2% (100mV increments)
* Hysteresis Range : VDF x 5%, TYP. (XC6101~XC6107)
                              VDF x 0.1%, TYP. (XC6111~XC6117)
* Operating Voltage Range : 1.0V ~ 6.0V
* Detect Voltage Temperature
* Characteristics : +100ppm/OC (TYP.)
* Output Configuration : N-channel open drain, CMOS
* Watchdog Pin : Watchdog input
- If watchdog input maintains ‘H’ or ‘L’ within the watchdog timeout period, a reset signal
is output to the RESET output pin
* Manual Reset Pin : When driven ‘H’ to ‘L’ level signal, the MRB pin voltage asserts forced reset on the output pin.
* Release Delay Time : 1.6sec, 400msec, 200msec, 100msec, 50msec, 25msec, 3.13msec (TYP.) can be selectable.
* Watchdog Timeout Period : 1.6sec, 400msec, 200msec, 100msec, 50msec, 6.25msec (TYP.) can be selectable.
