NX1117C / CE series

The NX1117C/NX1117CE are two series of low-dropout positive voltage regulators with an output current capability of 1 A. The two series consist of 18 fixed output voltage versions and two adjustable output voltage versions. NX1117C series offers an output voltage accuracy of ±1% and NX1117CE series of ±1.25 %.

The regulators feature output current limiting, Safe Operating Area (SOA) control, and thermal shutdown.

The NX1117C/NX1117CE series are housed in a medium power SOT223 (SC-73) Surface-Mounted Device (SMD) plastic package.

LD6805 series

The LD6805 series is a small size low-dropout regulator (LDO) family with a maximum voltage drop of 250 mV @ 150 mA current rating.

Offering a high PSRR (75 dB), an exceptionally low quiescent current (35 µA typ), and a standby current of just 0.1 µA, this LDO meets the demands of battery-driven circuits. Other features include an ultra-small lead-free SOT1194 (HXSON4) package, low noise (40 µVrms), excellent ESD immunity (7 kV HBM), and a low dropout voltage.

This series is ideal for use in applications requiring component miniaturization, such as mobile phone handsets, cordless telephones and personal digital devices
