NCP698
150 mA CMOS Ultra Low Iq
and IGND LDO Regulator
with Enable
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 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 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 mF. 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.
