The TPS7H1101-SP is a radiation-hardened LDO linear regulator that uses a PMOS pass element configuration. This device operates over a wide range of input voltage, from 1.5 V to 7 V while offering excellent PSRR. The TPS7H1101-SP features a precise and programmable foldback current limit implementation with a very-wide adjustment range. To support the complex power requirements of FPGAs, DSPs, or microcontrollers, the TPS7H1101-SP provides enable on and off functionality, programmable SoftStart, current sharing capability, and a PowerGood open-drain output.

PIN | I/O | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
SS | 1 | O | Soft-start terminal. Connecting an external capacitor slows down the output voltage ramp rate after enable event. The soft-start terminal can be used to disable the device as described in theSoft Start section. |
EN | 2 | I | Enable terminal. Driving this terminal to logic high enables the device; driving the terminal to logic low disables the device. VIN voltage must be greater than 3.5 V when using the EN pin. For VIN < 3.5 V, enable terminal cannot be used to disable the device. TI recommends to connect the enable terminal to VIN. |
VIN | 3 | I | Unregulated supply voltage. TI recommends to connect an input capacitor as a good analog circuit practice. |

PCL | 7 | O | Programmable current limit. A resistor to GND sets the overcurrent limit activation point. The range of resistor that can be used on the PCL terminal to GND is 8.2 kΩ to 160 kΩ. |
GND | 8 | — | Ground/thermal pad.(1) |
PG/OC | 9 | O | Power Good terminal. PG is an open-drain output to indicate the output voltage reaches 90% of target. PG terminal is also used as indicator when an overcurrent condition is activated. PG pin should have a pull-up resistor to the VOUT pin. |
CS | 10 | O | Current sense terminal. Resistor connected from CS to VIN. CS terminal indicates voltage proportional to output current.
CS terminal low: Foldback current limit disabled CS terminal high: Foldback current limit enabled |
VOUT | 11 | O | Regulated output. |

COMP | 15 | I | Internal compensation point for error amplifier. |
FB | 16 | I | The output voltage feedback input through voltage dividers. See Adjustable Output Voltage (Feedback Circuit) section. |
