AN6545, AN6545SP
Low Power Loss Voltage Regulators
n Overview
The AN6545 and AN6545SP are the voltage regulators
with strobe pin which can turn on/off an output.
A rated load current is 150mA and an output voltage is
fixed at 5V.
n Features
• 150mA rated load current and 5V fixed output voltage
• Capable of turning off an output by setting the strobe
pin to the “L” level
• Minimum input/output voltage difference:typ. 0.25V
• Built-in overcurrent protective circuit
• TO-126 (4-lead) package for the AN6545, and surface-
mount type 5-pin SIL plastic package for the AN6545SP
