NCP706B, NCP706AB
1 A, 1% Precision Very Low
Dropout Voltage Regulator
with Enable
The NCP706B/AB are a Very Low Dropout Regulators family
which provides up to 1 A of load current and maintains excellent
output voltage accuracy of 1% including line, load and temperature
variations. The operating input voltage range from 2.4 V up to 5.5 V
makes this device suitable for Li−ion battery powered products as well
as post−regulation applications. The product is available in 3.0 V fixed
output voltage option. NCP706B/AB are fully protected against
overheating and output short circuit and includes latched OCP
protection which automatically latches−off the device in the case of a
short circuit event and the NCP706AB has internal active discharge
circuit.
Very small 8−pin XDFN8 1.6 x 1.2, 04P package makes the device
especially suitable for space constrained portable applications such as
tablets and smartphones. Parts feature active output discharge
function.

PIN FUNCTION DESCRIPTION
Pin No.
XDFN8
Pin Name
Description
1
OUT
Regulated output voltage. A minimum 2.2 mF ceramic capacitor is needed from this pin to ground to
assure stability.
2 OUT
3 N/C Not connected. This pin can be tied to ground to improve thermal dissipation.
4
SNS
Remote sense connection. This pin should be connected to the output voltage rail.
5
GND
Power supply ground.
6 EN Enable pin. Driving EN over 0.9 V turns on the regulator. Driving EN below 0.4 V puts the regulator
into shutdown mode. In case of the NCP706B/AB pulling the EN low resets the OCP latch state.
7 IN Input pin. A small capacitor is needed from this pin to ground to assure stability.
8 IN
Exposed
This pad enhances thermal performance and is electrically connected to GND. It is recommended
Pad that the exposed pad is connected to the ground plane on the board or otherwise left open.
