NCP ma CMOS Ultra Low Iq and I GND LDO Regulator with Enable

Transcription

1 ma CMOS Ultra Low Iq and I GND LDO Regulator with Enable This series of fixed output lowdropout linear regulators are designed for handheld communication equipment and portable battery powered applications which require low quiescent and ground current. This series features an ultralow 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 NCP698 series provides an enable pin for ON/OFF control. The NCP698 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 microminiature SC82AB surface mount package. Standard voltage versions are 1.3, 1.5, 1.8, 2.5, 2.8, 3.0, 3.3, 3.5 and. Other voltages are available in 100 mv steps. Features Ultra Low Quiescent Current of 2.5 A Typical Output Voltage Accuracy of 2.0% Operating Temperature Range of 0 C to 85 C Enable Function This is a PbFree Device Typical Applications Battery Powered Instruments HandHeld Instruments Camcorders and Cameras Input + C1 GND Enable V in OFF ON + C2 Output SC82AB (SC70) SQ SUFFIX CASE 19C PIN CONNECTIONS & MARKING DIAGRAMS GND V in 1 2 xxxm ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 8 of this data sheet. 1 Top View) 3 Enable xxx = Specific Device Code M = Month Code* = PbFree Package (Note: Microdot may be in either location) *Date Code orientation and/or position and underbar may vary depending upon manufacturing location.
