NCP562/D
NCP562, NCP563
80 mA CMOS Low Iq
Low-Dropout Voltage
Regulator
This series of fixed output low−dropout linear regulators are
designed for handheld communication equipment and portable battery
powered applications which require low quiescent. 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 NCP562 series provides an
enable pin for ON/OFF control.
The NCP562/NCP563 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 1.5, 1.8, 2.1, 2.5, 2.7, 2.8, 3.0,
3.3, 3.5 and 5.0 V. Other voltages are available in 100 mV steps.
Features
• Low Quiescent Current of 2.5 A Typical
• Low Output Voltage Option
• Output Voltage Accuracy of 2.0%
• Temperature Range of −40°C to 85°C
• NCP562 Provides an Enable Pin
• Pb−Free Packages are Available
Typical Applications
• Battery Powered Instruments
• Hand−Held Instruments
• Camcorders and Cameras
