Low Dropout Linear
Regulator Controller
The NCP102 is a low dropout linear regulator controller for
applications requiring high-current and ultra low dropout voltages.
The use of an external N-Channel MOSFET allows the user to adapt
the device to a multitude of applications depending on system
requirements for current and dropout voltage.
An extremely accurate 0.8 V (±2%) reference allows the
implementation of sub 1 V voltage supplies. The reference is
guaranteed over the complete supply and temperature ranges.
Other features of the NCP102 are a dedicated enable input,
internally compensated error amplifier and an adjustable soft-start. A
minimum drive capability of ±5 mA provides fast transient response.
The drive current is internally limited to protect the controller in case
of an external MOSFET failure. The NCP102 is packaged in a space
saving TSOP-6.

PIN FUNCTION DESCRIPTION
Pin Symbol Name
Description
1 EN Enable Input (Active High). Pull the EN pin below 0.8 V to disable the regulator and enter the standby
mode operation.
2
GND
Ground
3 FB Inverting input of the error amplifier. The output voltage is sampled by means of a resistor divider and ap‐
plied to this pin for regulation.
4
SOFT-S
Programmable soft-start. An internal current source charges the capacitor connected to this pin. The soft-
start period ends once the voltage of the soft-start capacitor reaches 0.8 V.
5
DRV
Gate drive for external N-Channel MOSFET. It is also the buffered output of the error amplifier.
6 VCC Power supply voltage input. Operating voltage range is from 4.5 to 13.5 V. A decoupling capacitor to GND
should be used. A minimum of 0.1 mF is recommended.
