BM9168
BOOKLY MICRO
250mA CMOS LDO
GENERAL DESCRIPTION
FEATURES
The BM9168 family is a positive voltage linear regulator
developed utilizing CMOS technology featured low quiescent
current (10uA typ.), low dropout voltage, and high output
voltage accuracy. Built-in low on-resistance transistor provides
low dropout voltage and large output current. A 1.0µF or
greater can be used as an output capacitor.
Very Low Dropout Voltage
Low Current Consumption: Typ. <20uA
Output Voltage: 1.5V, 1.8V , 2.5V , 3.0V, 3.3V
High Accuracy Output Voltage: +/- 1.5%
Guaranteed >250mA Output
Input Range of 1.8V to 7.0V
Thermal Shutdown
The SOT-23-3 miniaturized package are recommended for
configuring portable devices and large current application,
respectively.
High PSRR to 55dB
Compact Package: SOT-23-3, SOT-89
Factory Pre-set Output Voltages
Short Circuit Current Fold-Back
Low Temperature Coefficient
These robust devices are designed to prevent device failure
under the worst operation condition with both Thermal
Shutdown and Current Fold-back.
