NCP612, NCV612
100 mA CMOS Low Iq
Voltage Regulator in an
SC70−5
The NCP612/NCV612 series of fixed output linear regulators are
designed for handheld communication equipment and portable battery
powered applications which require low quiescent. The
NCP612/NCV612 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 NCP612/NCV612 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, 3.1, 3.3, 3.7, and 5.0 V.
