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 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 NCP562 series provides an
enable pin for ON/OFF control.
The NCP562 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 1.5, 1.8, 2.5, 2.7, 2.8, 3.0, 3.3,
and 5.0 V. Other voltages are available in 100 mV steps.
Features
• Low Quiescent Current of 2.5 mA Typical
• Low Output Voltage Option
• Output Voltage Accuracy of 2.0%
• Temperature Range of –40°C to 85°C
• NCP562 Provides an Enable Pin
Typical Applications
• Battery Powered Instruments
• Hand–Held Instruments
• Camcorders and Cameras
