The LX8221 is a dual 150mA CMOS low dropout regulator from Microsemi. It features low dropout, fast transient performance, tight output voltage accuracy, and ultra-low ground current.
The Microsemi LX8221 family of dual output linear regulators provides a cost-effective power management solution for battery-driven applications. These regulators feature ultra-low ground current, fast transient performance, and tight output voltage accuracy within a compact 10-pin MSOP package footprint. They support both fixed and adjustable output voltage configurations, allowing for flexible system design.
| Input Voltage Range | 2.5 V to 6 V |
|---|---|
| Dropout Voltage | 175 mV @ 100 mA |
| Package Type | 10-pin MSOP |
| Operating Temperature | -40 to +125 °C |
| Ground Current (Shutdown) | < 1 µA |
The dropout voltage is typically 175 mV at a 100 mA load current.
The regulator requires an input operating voltage of at least 2.5 V to function correctly.
The device shuts down when the junction temperature exceeds approximately 170 °C.
