Fairchild Semiconductor International Inc. (San Jose, CA) announced its 150mA low dropout (LDO) regulator, the FAN2534, which optimizes performance and cost in cellular phone applications and is suitable for wireless/RF and frequency-sensitive applications. The new regulator offers high ripple rejection over a wide frequency range, fast turn-on (150µs), low noise (50µVrms) and loop stability with a variety of output capacitor types.
The FAN2534 offers fast turn-on without overshoot, as well as an accurate, trimmed, short-circuit, current limit (300mA) to protect thin PCB interconnects. For lower battery drain, the FAN2534 has 180mV dropout
voltage at 150mA, and provides near-dropout power supply rejection ratio, enable/shutdown control and thermal limiting for additional system safety. The FAN2534 is pin-for-pin compatible with competitive parts and comes in a compact SOT-23, five-lead package. Three
different output options are available for the device: adjustable, 2.6V with bypass and 3.0V with bypass.
Pricing for the FAN2534 is $0.39 for 1,000 pieces. Available now, delivery is eight weeks ARO.
