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

Verify the specific ordering suffix against official documentation to confirm package type and environmental compliance. Ensure that the selected component matches the required output voltage and functional configuration, particularly regarding the discharge shunt and pull-down resistor availability for the B-type series.

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

Select this component for applications requiring low dropout voltage and high ripple rejection. Consider the package power dissipation limits when designing for high output currents. Verify external capacitor requirements to prevent oscillation and ensure stable operation across the specified temperature range.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the S-1312 Series, which utilizes CMOS technology to achieve low current consumption and high accuracy. The series offers various output voltages selectable in 0.05 V steps and includes multiple package options such as SOT-23-5 and HSNT variants. The B-type specifically features an active 'H' ON/OFF logic with a discharge shunt function but without a pull-down resistor.
