6.3.5 Leakage Null Control Circuit

This device has a built-in, leakage-null control circuit. At high temperatures, pass-transistor leakage increases and starts impacting the VOUT accuracy at low-load conditions. This leakage becomes more aggravated with higher headroom across the LDO (VIN – VOUT). The TPS7B92 has a built-in, leakage-null control circuit that detects pass-transistor leakage and provides a ground discharge path for the leakage. This circuitry helps the TPS7B92 maintain much tighter VOUT accuracy across wide VIN and temperature (–40°C to +125°C) ranges.
