  1. 2008/04/25 HIP6211 - Dual Low Noise LDO in 3mm×3mm MLF™
 The HIP6211 is a dual CMOS low dropout linear regulator with ultra-low-noise output, very low
dropout voltage and very low ground current.
The HIP6211 operates from a 2.5V to 5.5V input voltage range and delivers up to 300mA, with low dropout of 150 mV at 300mA.
The other features of HIP6211 include short-circuit protection and thermal-shutdown protection.
Its dual channel and low noise feature is ideal for microcontroller and DSP based handheld
Other key application areas for HIP6211 also include palmtop computers, PCMCIA cards and
WLAN cards.
The HIP6211 has a special feature that if both EN pin is enabled simultaneously the output of LDO2 delays 20us from output of LDO1 which helps to minimize inrush startup current.
The HIP6211 is available in tiny 10pin 3mm x 3mm MLF (10L-TDLMF) package with fixed output voltage versions.
