CAT6217-280TDGT3

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

The CAT6217-280TDGT3 is a fixed-output low dropout regulator providing a nominal 2.80 V output with a guaranteed maximum load current of 150 mA. It operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 90 mV at full load. The device incorporates a quick-start feature, allowing the use of an external bypass capacitor for noise reduction without increasing turn-on time beyond 150 µs. It includes internal under-voltage lockout, thermal protection, and current limiting.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Quick-start functionality enables fast turn-on times while supporting external bypass capacitors for enhanced noise performance.
• Stable operation is maintained using small ceramic output capacitors, reducing board space requirements.
• Integrated protection mechanisms include output short-circuit current limiting, thermal shutdown, and under-voltage lockout.
