NCP512

80 mA CMOS Low Iq

Voltage Regulator in an

SC70−5

The NCP512 series of fixed output linear regulators are designed for

handheld communication equipment and portable battery powered

applications which require low quiescent. The NCP512 series features

an ultra−low quiescent current of 40

mA. Each device contains a

voltage reference unit, an error amplifier, a PMOS power transistor,

resistors for setting output voltage, current limit, and temperature limit

protection circuits.

The NCP512 has been designed to be used with low cost ceramic

capacitors. The device is housed in the micro−miniature SC70−5

surface mount package. Standard voltage versions are 1.5, 1.8, 2.5,

2.7, 2.8, 3.0, 3.3, and 5.0 V. Other voltages are available in 100 mV

steps.

Features

• Low Quiescent Current of 40 mA Typical

• Low Dropout Voltage of 250 mV at 80 mA

• Low Output Voltage Option

• Output Voltage Accuracy of 2.0%

• Industrial Temperature Range of −40°C to 85°C

Typical Applications

• Cellular Phones

• Battery Powered Consumer Products

• Hand−Held Instruments

• Camcorders and Cameras
