Under-Voltage Lockout (UVLO) The TPL730 series uses an under-voltage lockout circuit (UVLO = 1.9 V) to keep the output shut off until the internal circuitry operates properly. Regulated Output Voltage voltage is higher than VOUT (NOM) + VDO or 2.4 V, the output pin is the regulated output based on the selected voltage version. When the input voltage falls below VOUT (NOM) + VDO or 2.4 V, the output pin tracks the input voltage minus the dropout voltage based on the load current. When the input voltage drops below the UVLO threshold, the output keeps shut off. Adjustable Output Voltage The TPL730 series is also available in adjustable voltage versions of 0.8 V to 5 V by selecting suitable external resistor dividers. Use Equation 1 to calculate the output voltage (V FB = 0.8 V). Selecting the resistor value of (R1 + R2) between 10 kΩ and 100 kΩ is suggested. VOUT = VFB × 1 + R1 R2 (1) Current Limit The TPL730 series integrates an internal foldback current limit that helps to protect the regulator during fault conditions. When the output is shorted, the LDO supplies a typical current of 1000 mA. The output voltage is not regulated when the device is in current limit and is VOUT = ICL × RLOAD. Short-Circuit Protection The TPL730 series integrates the short-circuit protection. When the output pin is shorted to ground or forced to a voltage below 0.2 V, the output current of the TPL730 series is limited to a typical value of 150 mA. Thermal Shutdown During normal operation, the LDO junction temperature should not exceed 125°C. When the junction temperature exceeds the thermal shutdown threshold, the LDO shuts down the output immediately. Until when the junction temperature falls below the thermal shutdown threshold minus thermal shutdown hysteresis, the output turns on again.

During normal operation, the LDO junction temperature should not exceed 125°C. Use the below equations to calculate the power dissipation and estimate the junction temperature. The power dissipation can be calculated using Equation 2. PD = VIN − VOUT × IOUT + VIN × IGND (2) The junction temperature can be estimated using Equation 3. θJA is the junction-to-ambient thermal resistance (See Thermal Information). TJ = TA + PD × θJA (3) TPL730 Series 300-mA Output, High PSRR, Low-Dropout Linear Regulator www.3peak.com 15 / 24 DA20241001A6

• Both input capacitors and output capacitors must be placed as close to the pins of the device as possible.
• It is recommended to bypass the input pin to ground with a 0.1-μF bypass capacitor. The loop area formed by the bypass capacitor connection, the IN pin, and the GND pin of the system must be as small as possible.
• It is recommended to use wide trace lengths or thick copper weight to minimize I×R drop and heat dissipation. TPL730 Series 300-mA Output, High PSRR, Low-Dropout Linear Regulator www.3peak.com 16 / 24 DA20241001A6
