3 Description
The TPS7H1301SP, -SEP (TPS7H1301) and
TPS7H1302SP, -SEP (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.
