Description

The TPL8151Q is a 1.5-A high-current, low-dropout linear regulator with up to 29-V wide input voltage range. The TPL8151Q supports adjustable output voltage ranging from 1.25 V with an external resistor divider and is stable with a 10-μF to 100-μF tantalum output capacitor. The TPL8151Q is compatible with older three-terminal adjustable linear regulators but has lower dropout voltage, tighter output tolerance, and better transient performance. The TPL8151Q provides a thermal-enhanced ESOP8 package with guaranteed ambient operating temperature (TA) range from −40°C to +125°C.

(4) Dropout voltage is the minimum input to output voltage differential needed to maintain regulation at a specified output current and measure for VOUT ≥ 2.75 V. In dropout mode, the output voltage will be equal to VIN – VDO. TPL8151Q-S 1.5-A Wide-Input High-Current Low-Dropout Linear Regulator www.3peak.com 7 / 18 DA20230701A1

tolerance, and better transient performance. Figure 11. Functional Block Diagram the output voltage. Use Equation 1 to calculate the output voltage. Where the feedback voltage VREF is 1.25 V. output error. The resistor R1 should be put close to both the OUT pin and the ADJ pin. pulled down below the regulated voltage, the over-current protection starts to work and limits the output current. enough, it will cause over-temperature protection.

Over-Temperature Protection The over-temperature protection starts to work when the junction temperature exceeds the thermal shutdown threshold (T SD), which turns off the regulator immediately. When the device cools down, the junction temperature falls below a value, which equals to the thermal shutdown threshold minus thermal shutdown hysteresis, and the regulator turns on again. The junction temperature range should be limited according to the Recommended Operating Conditions table. Continuously operating above the junction temperature range will shorten the lifetime of the device.

• Both input and output capacitors must be placed as close to the device pins as possible, and vias between capacitors and device power pins must be avoided.
• 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 and thick copper to minimize I×R drop and heat dissipation. TPL8151Q-S 1.5-A Wide-Input High-Current Low-Dropout Linear Regulator www.3peak.com 13 / 18 DA20230701A1
