NCP551_06 Datasheet, PDF (1/11 Pages) ON Semiconductor – 150 mA CMOS Low Iq Low−Dropout Voltage Regulator

NCP551, NCV551
150 mA CMOS Low Iq
Low−Dropout 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−low 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−miniature TSOP−5 surface mount
package. Standard voltage versions are 1.5, 1.8, 2.5, 2.7, 2.8, 2.9, 3.0,
3.1, 3.2, 3.3, and 5.0 V. Other voltages are available in 100 mV steps.
Features
• Low Quiescent Current of 4.0 mA Typical
• Maximum Operating Voltage of 12 V
• Low Output Voltage Option
• High Accuracy Output Voltage of 2.0%
• Industrial Temperature Range of −40°C to 85°C
(NCV551, T_A = −40°C to +125°C)
• NCV Prefix for Automotive and Other Applications Requiring Site
and Control Changes
• Pb−Free Packages are Available
Typical Applications
• Battery Powered Instruments
• Hand−Held Instruments
• Camcorders and Cameras
