MC78PC00 Series

Low Noise 150 mA

Low Drop Out (LDO)

Linear Voltage Regulator

The MC78PC00 are a series of CMOS linear voltage regulators with

high output voltage accuracy, low supply current, low dropout voltage,

and high Ripple Rejection. Each of these voltage regulators consists of

an internal voltage reference, an error amplifier, resistors, a current

limiting circuit and a chip enable circuit.

The dynamic Response to line and load is fast, which makes these

products ideally suited for use in hand−held communication

equipment. The MC78PC00 series are housed in the SOT−23 5 lead

package, for maximum board space saving.
