NCP152
Dual 150 mA, Low I
Q
, Low
Dropout Voltage Regulator
The NCP152 is 150 mA, Dual Output Linear Voltage Regulator that
provides a very stable and accurate voltage with very low noise and
high Power Supply Rejection Ratio (PSRR) suitable for RF
applications. The device doesn’t require any additional noise bypass
capacitor to achieve very low noise performance. In order to optimize
performance for battery operated portable applications, the NCP152
employs the Adaptive Ground Current Feature for low ground current
consumption during light−load conditions.

Description
Regulated output voltage of the first channel. A small 0.22
mF
ceramic capacitor is needed from this pin to
ground to assure stability.
Regulated output voltage of the second channel. A small 0.22
mF
ceramic capacitor is needed from this pin
to ground to assure stability.
Power supply ground. Soldered to the copper plane allows for effective heat dissipation.
Driving EN2 over 0.9 V turns−on OUT2. Driving EN below 0.4 V turns−off the OUT2 and activates the active
discharge.
Input pin common for both channels. It is recommended to connect 0.22
mF
ceramic capacitor close to the
device pin.
Driving EN1 over 0.9 V turns−on OUT1. Driving EN below 0.4 V turns−off the OUT1 and activates the active
discharge.
Exposed pad must be tied to ground. Soldered to the copper plane allows for effective thermal dissipation.
