Instructions for Using TL7712ACD:
Power Supply Connection:
- Connect the input voltage (V_IN) between 2.7V and 5.5V to the VIN pin.
- Ensure a stable power supply to avoid fluctuations.
Output Configuration:
- The output voltage (V_OUT) is fixed at 1.8V. Connect your load between the VOUT pin and GND.
Quiescent Current Management:
- The device has a quiescent current of typically 30渭A, which helps in maintaining efficiency even under light loads.
Shutdown Feature:
- To put the device into shutdown mode, apply a low signal to the SHDN pin. This reduces the current consumption to about 0.1渭A.
Load Handling:
- The device can handle up to 150mA of load current. Ensure that the load does not exceed this limit to prevent damage.
Dropout Voltage Consideration:
- The dropout voltage is approximately 200mV. Make sure the input voltage is sufficiently higher than the output voltage by at least this amount.
Power Supply Rejection Ratio (PSRR):
- The device provides a PSRR of 60dB, effectively rejecting noise from the power supply lines.
Temperature Range:
- Operate the device within the temperature range of -40掳C to +85掳C to ensure reliable performance.
Capacitor Selection:
- Choose appropriate input and output capacitors as specified in the datasheet to stabilize the output voltage and improve transient response.
Note: Always refer to the official Texas Instruments datasheet for detailed specifications and application notes.
