BM9166
250mA CMOS LDO
GENERAL DESCRIPTION
FEATURES
The BM9166 family is a positive voltage linear regulator
ꢀ
Very Low Dropout Voltage
Low Current Consumption: Typ. <55uA
developed utilizing CMOS technology featured low quiescent ꢀ
current (<55uA typ.), low dropout voltage, and high output ꢀ
voltage accuracy. Built-in low on-resistance transistor provides ꢀ
Output Voltage: 1.5V, 2.5V , 3.0V, 3.3V
High Accuracy Output Voltage: +/- 1.5%
Guaranteed >200mA Output
Input Range of 1.8V to 7.0V
low dropout voltage and large output current. A 2.2µF or
greater can be used as an output capacitor.
