XC6501B171NR-G

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The XC6501B171NR-G is a high-speed, low-noise CMOS LDO regulator manufactured by Torex Semiconductor. It provides a fixed output voltage of 1.7V with a maximum output current of 200mA. The device operates within an input voltage range of 1.4V to 6.0V and achieves stable regulation without requiring an external load capacitor due to internal phase compensation. Key electrical parameters include a typical dropout voltage of 230mV at 100mA, a supply current of 13μA, and a ripple rejection ratio of 50dB at 1kHz. The component features a CE pin for standby control and includes built-in current limit and short-circuit protection circuits.
