SENSE – Fixed voltage options only  
(TPS7325, TPS7330, TPS7333, TPS7348, and TPS7350)  
The TPS73xx devices are members of a family of  
micropower low-dropout (LDO) voltage regulators.  
‡
FB – Adjustable version only (TPS7301)  
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 TPS71xx and TPS72xx should be considered.

The D and PW packages are available taped and reeled. Add an R suffix to device type (e.g., TPS7350QDR). The TPS7301Q is programmable  
using an external resistor divider (see application information). The chip form is tested at 25°C.  
§
The TPS7325 has a tolerance of ±3% over the full temperature range.  
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.
