Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific product type code 'C' configuration, which indicates unavailable discharge shunt function and available pull-down resistor functionality. Confirm that the HSNT-4(1010)B package designation matches the required footprint for the target design. Ensure compliance with the specified operating temperature range and thermal dissipation limits before finalizing procurement orders.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 2.7 V output is required for automotive environments. The C-type variant is appropriate if a pull-down resistor is needed during power-off but discharge shunt functionality is not required. Consider the HSNT-4(1010)B package for applications demanding super-small surface-mount mounting density compared to standard SOT-23-5 options.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the soft-start behavior for the S-19252C27H-A4T7U4?

The S-19252C27H-A4T7U4 features a fixed soft-start time of approximately 0.1 ms. Unlike J/K/L/M types, it does not have a switchable SST pin for adjusting this duration.

Does this regulator support discharge shunt function?

No, the 'C' product type designation indicates that the discharge shunt function is unavailable. However, it does include a pull-down resistor function.
