CS8129 is a 5V, 750mA low dropout linear regulator with a lower reset threshold, suitable for use with 4V microprocessors. It has a low dropout voltage, high output current capability, and provides fault protection.
The CS8129 is a precision 5V linear regulator capable of sourcing up to 750mA. It features a reduced RESET threshold voltage of 4.2V, allowing operation with 4V microprocessors and under low battery conditions. The device includes fault protection against reverse battery, overvoltage, short circuits, and thermal runaway.
| Output Voltage | 5.0V +/- 3% |
|---|---|
| Output Current Capability | 750mA |
| Dropout Voltage (at 500mA) | 0.6V max |
| RESET Threshold (Increasing) | 4.2V typ |
| Delay Time (with 0.1uF capacitor) | 16ms to 48ms |
The regulated output voltage is nominally 5.0V with a tolerance range from 4.85V to 5.15V.
Yes, the RESET threshold has been lowered to 4.2V to allow use with 4V microprocessors.
The delay time is externally programmed using a discrete RC network connected to the Delay lead.
