- 2.5Ω (typical) inverter output impedance, VIN = 5V
- ±1.5% regulation output accuracy
- 500kHz (typical) fixed-frequency, adjustable negative output voltage operation (TPS7H1301)
- 1MHz (typical) fixed-frequency, fixed –1.8V output (TPS7H1302)
- 45dB (typical) LDO PSRR at 100kHz with 100mA load current
- Plastic packages outgas tested per ASTM E595

The TPS7H1301 and TPS7H1302 are charge pump positive-to-negative voltage inverters with an integrated negative low dropout regulator (LDO). Both devices accept a positive input supply voltage range of 3V to 6.3V and deliver up to 400mA of output current, with integrated enable and power-good functionality.
The TPS7H1301 features a 500kHz (typical) charge pump switching frequency and provides adjustable output voltage regulation. Its STAB pin enables direct access to the negative LDO error amplifier for external compensation, offering design flexibility for optimized transient response.
The TPS7H1302 delivers a fixed –1.8V output voltage with a 1MHz (typical) charge pump switching frequency. By eliminating the need for external feedback resistors, the TPS7H1302 reduces both external component count and overall solution size.
