Description
This series of fixed output low?dropout linear regulators are
designed for handheld communication equipment and portable battery
powered applications which require low quiescent and ground current.
This series features an ultra?low quiescent current of 2.5 A. 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 NCP698 series provides an
enable pin for ON/OFF control.
The NCP698 has been designed to be used with low cost ceramic
capacitors and requires a minimum output capacitor of 0.1 F. The
device is housed in the micro?miniature SC82?AB surface mount
package. Standard voltage versions are 1.3, 1.5, 1.8, 2.5, 2.8, 3.0, 3.3,
3.5 and 5.0 V. Other voltages are available in 100 mV steps.
