CAT6218
Overview
The CAT6218 is a 300mA CMOS low dropout regulator that provides fast response time during load current and line voltage changes. The quick-start feature allows the use of an external bypass capacitor to reduce the overall output noise without affecting the turn-on time of just 150μs.
- Guaranteed 300mA output current
- Low dropout voltage of 180mV typical at 300mA
- Stable with 1μF ceramic output capacitor
- External 10nF bypass capacitor for low noise
- Quick-start feature
- No-load ground current of 55μA typical
- Full-load ground current of 80μA typical
- ±1.0% initial accuracy (VOUT ≥ 2.0V)
- ±2.0% accuracy over temperature (VOUT ≥ 2.0V)
- “Zero” current shutdown mode
