150mA Low-Noise LDO
Voltage Regulator

CLM5205
FEATURES
GENERAL 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.
