SC560CULTRT

SC560CULTRT is a dual output low noise LDO. It is a dual-output, ultra-low dropout linear voltage regulator designed for use in battery-powered wireless applications. It provides adjustable output voltages that can be set using two external resistors. Fixed output devices provide the power good monitor, independent enable pins, and a bypass pin for low-noise operation. It uses this pin to provide a PGOOD output to hold a processor in reset when the voltage on OUTA is not in regulation. All other versions provide all three functions with # xed output voltages (no feedback pins are provided). The device also provides protection circuitry such as current limiting, under-voltage lockout, and thermal protection to prevent device failures. Typical applications are PDAs and cellular phones, GPS devices, palmtop computers and handheld instruments, TFT/LCD applications, wireless handsets, digital cordless phones and PCS phones, personal communicators, wireless LAN.

• Stability is maintained by using 1µF capacitors on the output pins
• Input voltage range from 2.5V to 5.5V
• Over-temperature protection, short-circuit protection, under-voltage lockout
• Dropout at 200mA load is 200mV maximum
• Shutdown current is 100nA (typical)
• MLPQ-UT8 1.5×1.5 package
• Ambient temperature range from -40 <lt/> TA <lt/> +85°C
• Maximum output current is 300mA
