description
The TPS73xx devices are members of a family
of micropower low-dropout (LDO) voltage
regulators. They are differentiated from the
TPS71xx and TPS72xx LDOs by their integrated delayed microprocessor-reset function. If the precision
delayed reset is not required, the designer should consider the TPS71xx and TPS72xx.

The D package is available taped and reeled. Add R suffix to device type (e.g., TPS7350QDR). The PW package is only available left-end taped
and reeled. The TPS7301Q is programmable using an external resistor divider (see application information). The chip form is tested at 25
°
C.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
§The TPS71xx and the TPS72xx are 500-mA and 250-mA output regulators respectively, offering performance similar to that of the TPS73xx
but without the delayed-reset function. The TPS72xx devices are further differentiated by availability in 8-pin thin shrink small-outline
packages (TSSOP) for applications requiring minimum package size.
