NCP662, NCV662, NCP663, NCV663

100 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 current. 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 NCP662/NCV662 series provides an enable pin for ON/OFF control.

This series 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, 2.5, 2.7, 2.8, 3.0, 3.3, and 5.0 V.

Features

• Low Quiescent Current of 2.5 A Typical

• Low Output Voltage Option

• Output Voltage Accuracy of 2.0%

• Temperature Range for NCV662/NCV663 −40°C to 125°C

Temperature Range for NCP662/NCP663 −40°C to 85°C

• NCP662/NCV662 Provides as Enable Pin

• NCV Prefix for Automotive and Other Applications Requiring Site

and Control Changes

• Pb−Free Packages are Available

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously . If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.
