NCP785AH150T1G

Product Overview

The onsemi NCP785AH150T1G is a positive fixed-output linear voltage regulator in a surface-mount package. It provides a single 15 V output at up to 10 mA, with a maximum input voltage rating of 450 V. The device includes over-current and over-temperature protection and is specified for operation from -40°C to 85°C. Its 22 µA quiescent current and 70 dB PSRR at 1 kHz support compact low-current regulation tasks where a fixed 15 V rail is required. The package is TO-243AA with a SOT-89-3 footprint.

Key Features

• Positive fixed 15 V output with a 10 mA output current capability.
• Maximum input voltage of 450 V for high-voltage to low-current regulation.
• 22 µA quiescent current and 70 dB PSRR at 1 kHz.
• Over-current and over-temperature protection in a TO-243AA SOT-89-3 surface-mount package.
• Single regulator with surface-mount mounting type.

Applications

• Low-current 15 V supply for control logic or interface circuits.
• Bias supply for small analog modules.
• Regulation from a high-voltage input to a fixed 15 V output in compact board areas.

Design & Procurement Notes

When selecting this regulator, verify that the load current remains within 10 mA and that the input voltage does not exceed the 450 V maximum rating. The fixed 15 V output is not adjustable, so system voltage requirements should match this value. The 22 µA quiescent current supports low-power standby conditions, while the 70 dB PSRR at 1 kHz can help reduce input ripple in low-current circuits. Over-current and over-temperature protection are included, but thermal design should still account for the -40°C to 85°C operating range and the SOT-89-3 surface-mount footprint. Because the device has a single output, additional rails require separate regulation.
