Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for AP7381-70V-A
Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview
The AP7381-70V-A is a positive voltage regulator IC from the AP7381 series, manufactured by Diodes Incorporated. It provides a fixed 7.0V output with a maximum continuous current of 150mA. The device supports an input voltage range from 3.3V to 40V and operates within a junction temperature range of -40°C to +125°C. It utilizes a TO92 package with Ammo Packing. Key electrical characteristics include a dropout voltage of 1000mV at 100mA (for 3.3V versions), a ground current of 2.5µA at no load, and a thermal shutdown threshold of +160°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes
Verify the specific suffix 'V' indicates the TO92 Ammo Packing variant, as this package type is explicitly marked as not recommended for new designs in official documentation. Confirm that the 70V designation corresponds to the 7.0V fixed output version. Ensure compliance with RoHS 3 standards and check for any discontinuation notices associated with legacy packaging options before finalizing procurement plans.
Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes
Select this component when a fixed 7.0V rail is required from inputs up to 40V. The TO92 Ammo Packing form factor suits through-hole assembly but may limit board space efficiency compared to SOT23 or SOT89 alternatives. Consider the 150mA current limit and 1000mV dropout voltage against load requirements. Evaluate thermal resistance values if high ambient temperatures are expected in the application environment.
Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context
The AP7381 series comprises wide input voltage LDO regulators designed for USB and portable applications. This specific part belongs to the family offering fixed output voltages including 2.8V, 3.3V, 5.0V, and 7.0V. While the series supports multiple packages like SOT23 and SOT89, the AP7381-70V-A specifically utilizes the older TO92 Ammo Packing configuration, which is distinct from the surface-mount options available in the same product line.
