Nexperia Current Regulator 0.015mA to 50mA Output 75V SOT-353

The Nexperia Current Regulator is a one-chip constant current source with an adjustable output from 15 μA to 50 mA and a maximum supply voltage of 75V.

Overview

This regulator integrates a resistor-equipped PNP transistor with two diodes on a single chip. The output current is set by connecting one external resistor between pins 4 and 5, which offers flexibility in circuit design. Because these elements are combined in one device, it is intended to reduce component count and save board space in compact electronic designs.

Key Features

• Integrated design: a complete constant current source on a single chip
• Adjustable output: 15 μA (0.015 mA) to 50 mA using a single external resistor
• High voltage capability: maximum supply voltage of 75V with an output voltage up to 73V
• Power handling: maximum power dissipation (Pd) of 335 mW
• Wide ambient temperature range: -65°C to +150°C
• Compact package: SC-88A (SOT-353) plastic SMD with 5 leads, suitable for automated surface-mount assembly

Applications

The constant current source is suitable for demanding applications, including automotive electronic systems where reliability under extreme conditions is critical. It can be used as a generic constant current source for biasing and reference circuits, as a constant current LED driver for consistent illumination, and for active bias control in audio amplifiers.

Choose the Nexperia Current Regulator when a compact, single-chip constant current source with a 75V supply rating and a 15 μA to 50 mA adjustable output is required for your design.
