Features: The main characteristics and advantages of TPS7A30 and TPS7A49: The wide input voltage range is supported by high line voltage transient high robust tolerance: TPS7A30 is -3.0V to -36V, and TPS7A49 is +3.0V to +36V; Under the condition of full load and full input voltage, the nominal precision is 1.5%, which can achieve higher precision for VCO, and ADC. The high stability in combination with a ceramic output capacitor greater than 2uF can achieve a smaller size and lower cost than the tantalum capacitor. Low noise / high power supply rejection ratio (PSRR) can significantly improve the effective range of RF applications, and DC/DC burr processing. The module can suppress the input ripple and noise effectively and reduce the output ripple and noise. At 1kHz, PSRR is 72dB; 10kHz to 700kHz, PSRR is 55dB Specification: Module power supply: ±4~±36V Output noise:15uV Max current: 0.15A Absolute value of output voltage < absolute value of input voltage -1V Output voltage: ±5V Size: 4*4cm/1.6*1.6in Weight: Approx.12g/0.4oz Package includes: 1 x Positive and negative power supply
