onsemi Voltage Regulators - Linear MC33761SNT1-030

The MC33761SNT1-030 is a low dropout (LDO) voltage regulator designed for applications requiring ultra-low noise performance. It achieves a noise level of 40 ¬µVRMS without the need for an external bypass capacitor, making it suitable for noise-sensitive circuits such as VCOs and RF stages. The device operates with a nominal output current of 80 mA and can handle peak currents up to 100 mA. It features a fast response time of 40 ¬µs from OFF to ON, which is beneficial for portable applications. The regulator has a typical dropout voltage of 90 mV at 30 mA and 160 mV at 80 mA, with a static line regulation better than -75 dB, ensuring stable output under varying input conditions. It supports output voltages of 2.8 V and 2.9 V, with a ripple rejection of 70 dB at 1 kHz. The operating temperature range is from -40¬8C to +85¬8C, and the device includes thermal shutdown protection. The MC33761SNT1-030 is housed in a compact SOT-23 package, making it an ideal choice for space-constrained designs.
