TC9162N Parameter Table

Instructions for Using the TC9162N

1. Pin Configuration:

   • VIN (Pin 1): Input voltage.
   • GND (Pin 2): Ground.
   • VOUT (Pin 3): Output voltage.
   • SHDN (Pin 4): Shutdown control. Connect to GND to enable the regulator; connect to VIN to disable it.

2. Output Voltage Adjustment:

   • The output voltage can be adjusted using two external resistors, R1 and R2, connected between VOUT and GND.
   • The formula for calculating the output voltage is: [ V_ = V_ left(1 + fracright) ]
   • Where ( V_ ) is typically 1.2 V.

3. Capacitor Requirements:

   • Input Capacitor (CIN): A 1 μF ceramic capacitor should be placed as close as possible to the VIN and GND pins to stabilize the input voltage.
   • Output Capacitor (COUT): A 10 μF tantalum or ceramic capacitor should be placed between VOUT and GND to stabilize the output voltage.

4. Thermal Considerations:

   • Ensure adequate heat dissipation if the device is operating at high current or in high ambient temperatures.
   • The thermal resistance (θJA) is typically 50°C/W for the SOT-23 package.

5. Shutdown Mode:

   • To put the regulator into shutdown mode, connect the SHDN pin to VIN. This will reduce the quiescent current to approximately 1 μA.

6. Layout Recommendations:

   • Keep the PCB traces short and wide to minimize inductance and resistance.
   • Place bypass capacitors as close as possible to the IC to ensure stability.

7. Application Notes:

   • The TC9162N is suitable for applications requiring a stable output voltage with low dropout and low quiescent current.
   • It is commonly used in battery-powered devices, portable electronics, and other low-power systems.

By following these instructions, you can effectively use the TC9162N in your designs.
