The HT79L05ARZ with SOP-8 Linear Voltage Regulators, is an ultra-low noise LDO (Low Drop Out) voltage regulator IC manufactured by HTCSEMI. This unit offers very low noise at 1.2µVRMS or better for input voltages of 1.2V or more and outputs of 2A. The HT79L05ARZ is designed for applications such as RGB LED lighting, WLED constant current power supplies, portable audio and data device power supply, and low noise power supplies with stringent noise specs. The device is ROHS Compliant and offers a wide operating temperature range (-40 to 125°C). It features soft-start, output short-circuit protection, under and over temperature protection, and output voltage accuracy of ±1.5%. It also offers very low quiescent current allowing up to 96% efficiency.
