AP7381-70Y-13

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

The AP7381-70Y-13 is a positive voltage regulator IC from the AP7381 series, manufactured by Diodes Incorporated. It provides a fixed output voltage of 7V with a maximum output current of 150mA. The device supports a wide input voltage range from 3.3V to 40V and operates within a junction temperature range of -40°C to +125°C. Packaged in an SOT-89-3 surface-mount format, it features low dropout voltage (1000mV at 100mA), ultra-low quiescent ground current (2.5µA typical), and high output voltage accuracy. Integrated protections include thermal shutdown and short-circuit protection.

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

Verify component authenticity through authorized channels as the AP7381-70Y-13 may be subject to discontinuation notices. Confirm package type matches SOT-89-3 and check RoHS compliance status. Ensure ordering suffixes align with specific packaging requirements such as tape and reel quantities. Validate that the supplier provides traceability documentation consistent with Diodes Incorporated standards.

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

Select this component when a fixed 7V output is required with a wide input voltage capability up to 40V. It is suitable for applications demanding low power consumption due to its minimal ground current. Consider the SOT-89-3 package for space-constrained designs requiring surface mount technology. Ensure the load current does not exceed 150mA and verify thermal management capabilities for the operating environment.
