FEATURES
GENERAL DESCRIPTION
Ultra-Low Noise Output
High Output Voltage Accuracy
Guaranteed 150mA Output
Low Quiescent Current
Low Dropout Voltage
Extremely Tight Load and Line Regulation
Very Low Temperature Coefficient
Current and Thermal Limiting
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.
