GENERAL DESCRIPTION
The XC6222 series is a highly accurate, low noise, high ripple rejection, low dropout, and low power consumption high speed CMOS voltage regulator. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a thermal protection circuit, a reverse current protection circuit and a phase compensation circuit.
The CE function enables the entire circuit to be placed in a stand-by state by inputting a low level signal to the CE pin. In this stand-by mode, the electric charge at the output capacitor (CL) will be discharged by the internal auto-discharge switch, and as a result the VOUT pin will quickly return to the VSS level.
Over-current protection and thermal protection circuits are integrated. The protection circuit starts to operate when either output current reaches the current limit level or junction temperature reaches the temperature limit. With the reverse current protection function, the reverse current flow is prohibited when VOUT voltage is higher than VIN voltage. The device is optimized for use in backup power circuits.

FEATURES
*Dropout Voltage : 120mV @IOUT=300mA(VOUT=3.0V)
*Operating Voltage Range : 1.7V ~ 6.0V
*Output Voltages : 0.8V~5.0V (0.05V increments)
*Accuracy : +1% (VOUT>2.0V), +0.02V (VOUT≦2.0V)
*Low Power Consumption : 100μA (VOUT=3.0V)
*Stand-by Current : Less than 0.1μA
*High Ripple Rejection : 65dB @ 1kHz
*Operating Temperature : -40℃~+85℃

Description
The L5973D is a step down monolithic power switching regulator with a minimum switch current limit of 2.5 A so it is able to deliver more than 2 A DC current to the load depending on the application conditions.
The output voltage can be set from 1.235 V to 35 V. The high current level is also achieved thanks to an SO8 package with exposed frame, that allows to reduce the Rth(j-amb) down to approximately 40 °C/W.
The device uses an internal P-channel D-MOS transistor (with a typical Rdson of 250 mΩ) as switching element to minimize the size of the external components.
An internal oscillator fixes the switching frequency at 250 kHz.
Having a minimum input voltage of 4 V only, it is particularly suitable for 5 V bus, available in all computer related applications.
Pulse by pulse current limit with the internal frequency modulation offers an effective constant current short circuit protection.

Features
*2.5 A internal switch
*Operating input voltage from 4 V to 36 V
*3.3 V / (±2%) reference voltage
*Output voltage adjustable from 1.235 V to 35 V
