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.
Features
• Wide Operating Voltage Range to 12 V
• Internally Set Output Voltages
• Enable Pin for On/Off Control
• UVLO on the Input Voltage with Hysteresis
• Current and Thermal Protection
• Compatible with Ceramic, Tantalum or Aluminum Electrolytic
Capacitors
• Pb−Free Package is Available

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
