Status: In Production
The LX8213 LDO regulator is a positive voltage regulator ICs using CMOS technology. The device provides a compact and cost effective solution featuring low power consumption over a wide supply voltage range, high output voltage accuracy, low dropout, excellent line and load regulation, fast transient response, and low noise. The LX8213 operates over a wide input voltage range of 2.5V to 6V, and consumes only 60uA typical quiescent current at no load and a low 0.1uA shutdown current. Output voltage options include fixed 1.2V, 3.3V, or an adjustable output voltage which may be set from 1.2V to 5.5V. The LDO delivers up to 300mA of output current, with a foldback current limit of approximately 400mA. At 300mA load, dropout voltage measures only 170mV for a 3.3V output. Tight load and line regulation is achieved over the full output current and supply range. The high bandwidth control loop provides fast transient response to reduce output voltage deviation using low cost external ceramic capacitors in the 1uF range.
The LX8213 also exhibits low output noise with only 60uVRMS over a 100kHz bandwidth. Power supply rejection exceeds 65dB at 100Hz. Other features of LX8213 include an active low shutdown input with a 3MΩ internal pull-down for low cost power sequencing, internal soft-start circuitry to prevent inrush current, short circuit current limit, and thermal overload protection. The LX8213 operates over -40˚C to +85˚C ambient temperature range and is available in a tiny 5 pin SOT-23 ROHS compliant package.
