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鈭抦iniature TSOP鈭? surface mount package. The NCP5426 is
available in output voltages of 1.2 V to 2.0 V in 0.1 V increments.
