NCV511 Voltage Regulator Datasheet
Low-Dropout Voltage Regulator
|Total Page||11 Pages|
Voltage Regulator - CMOS,
Low Iq, Low-Dropout
The NCP511 series of fixed output low dropout linear regulators are
designed for handheld communication equipment and portable battery
powered applications which require low quiescent current. The
NCP511 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 NCP511 has been designed to be used with low cost ceramic
capacitors and requires a minimum output capacitor of 1.0 mF. The
device is housed in the micro−miniature TSOP−5 surface mount
package. Standard voltage versions are 1.5 V, 1.8 V, 2.5 V, 2.7 V, 2.8 V,
3.0 V, 3.3 V, and 5.0 V. Other voltages are available in 100 mV steps.
