NCP561
150 mA CMOS Low Iq
Low−Dropout Voltage
Regulator
The NCP561 series of fixed output low dropout linear regulators are
designed for handheld communication equipment and portable battery
powered applications which require low quiescent. The NCP561
series features an ultralow quiescent current of 3.0 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 NCP561 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.
Features
• Low Quiescent Current of 3.0 mA Typical
• Low Dropout Voltage of 170 mV at 150 mA
• Low Output Voltage Option
• Output Voltage Accuracy of 2.0%
• Industrial Temperature Range of −40°C to 85°C
• Pb−Free Packages are Available
Typical Applications
• Battery Powered Instruments
• Hand−Held Instruments
• Camcorders and Cameras
