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

Verify the specific output voltage code (34 for 3.4 V) and logic type (B for positive logic ON/OFF pin) against design requirements. Confirm package availability in HSOP-6 tape format. Ensure application conditions do not exceed the specified power dissipation limits for the mounting environment. Contact ABLIC Inc. directly for use in automobile control units or medical equipment as required by safety guidelines.

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

Select this component when a high input voltage tolerance up to 50 V is required alongside low quiescent current. The B-type designation indicates positive logic for the ON/OFF pin, suitable for active-high enable signals. Consider the thermal resistance of the HSOP-6 package when designing for high load currents to prevent thermal shutdown activation. Verify that external capacitors meet the minimum capacitance requirements for stability.

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

This part belongs to the S-1142A/BxxH series of CMOS voltage regulators designed for automotive and industrial environments. The series is characterized by its ability to operate at elevated temperatures up to 105°C and its robustness against high input voltages. The 'H' suffix denotes the automotive-grade temperature range, while 'E6T2' specifies the HSOP-6 package and tape packing configuration.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

For applications sensitive to output voltage overshoot during power-on, consider the S-1142C/DxxH Series as an alternative. Other parts within the S-1142A/BxxH family with different output voltages or ON/OFF logic types (A vs. B) may serve as direct replacements if pin compatibility and voltage levels match.
