NCP512 Datasheet, PDF (1/10 Pages) ON Semiconductor – 80 mA CMOS Low Iq Voltage Regulator in an SC70-5

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
