NCP5426

LDO Regulator/Vibration

Motor Driver

The NCP5426 series of fixed output, 150 mA low dropout linear

regulators are designed to be an economical solution for a variety of

applications. Each device contains a voltage reference unit, an error

amplifier, a PNP power transistor, resistors for setting output voltage,

an under voltage lockout on the input, an enable pin, and current limit

and temperature limit protection circuits.

The NCP5426 is designed for driving a vibration motor using

ceramic capacitors on the output. The device is housed in the

micro−miniature TSOP−5 surface mount package. The NCP5426 is

available in output voltages of 1.2 V to 2.0 V in 0.1 V increments.
