NCP551, NCV551
150 mA CMOS Low Iq
Low鈭扗ropout Voltage
Regulator
The NCP551 series of fixed output low dropout linear regulators are
designed for handheld communication equipment and portable battery
powered applications which require low quiescent. The NCP551
series features an ultra鈭抣ow quiescent current of 4.0
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 NCP551 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鈭抦iniature TSOP鈭? surface mount
package. Standard voltage versions are 1.5, 1.8, 2.5, 2.7, 2.8, 3.0, 3.2,
3.3, and 5.0 V. Other voltages are available in 100 mV steps.
