SAN JOSE, Calif.--(BUSINESS WIRE)--April 16, 2001

Fairchild Semiconductor International (NYSE:FCS) introduces a new family of cost-effective CMOS low dropout voltage regulators (LDOs) for battery-powered portable applications, including CDMA, TDMA and GSM cellular phone handsets, PDAs, MP3 players, laptop and notebook computers, digital cameras, camcorders and other portable electronic devices.

The FAN250x and FAN251x series has very low ground current (25uA at 50mA) and very low dropout voltage (50mV at 50mA) to provide ultra-low power consumption that extends battery life.

The FAN250x and FAN251x series is offered in 50mA, 100mA, 150mA and 200mA versions with adjustable, 2.5V, 2.6V, 2.7V, 2.8V, 2.85V, 3.0V and 3.3V options. Additional options include a bypass capacitor for enhanced noise performance, an under-voltage error flag usable as a power-good indicator and fast start enable for applications requiring fast turn-on, like cell phones. All are supplied in the industry-standard SOT-23-5 surface-mount package and pin-out.

Other features include exceptional loop stability that enables operation with all types of low cost capacitors (e.g. ceramic), low shut down current (1uA), 2 percent accuracy over the full temperature range, and thermal overload protection.
