Description

The Calogic CLM5205 is a low noise, low dropout voltage regulator featuring ultra low ground current (800uA at 100mA output) and tighter than 1% initial accuracy with a logic compatible ON/OFF switching input.  Designed for hand-held battery powered devices, the CLM505 is switched by a CMOS or TTL compatible logic signal.  When disabled, power consumption drops nearly to zero.  Prolonging battery life, the ground current of the CLM5205 increases only slightly in dropout. Major features of the CLM5205 include a reference bypass pin for excellent low-noise performance, protection against reversed battery, current limiting, and overtemperature shutdown.
The CLM5202 is available in several fixed voltages and an adjustable output voltage version in a small SOT-23-5 package.  The pinout is smaller to the LP2980 with significantly better performance.
