Description

The TPL8601Q is a series of low-dropout linear regulators with 150-mA maximum output current capability. The TPL8601Q series supports an operating voltage range from 3.5 V to 42 V ( −40 V to 45 V maximum operating voltage range). Operating with as low as 3.5 V allows the TPL8601Q to continue to work well during cold-crank and start-stop conditions. The TPL8601Q supports an output capacitor range from 1 μF to 100 μF with an ESR range from 0.001 Ω to 5 Ω. The TPL8601Q integrates full protection with input reverse polarity protection, output short-circuits to ground protection, output short-circuits to battery protection, inductive clamp at the OUT pin, over-current protection, and over-temperature protection. With all the above features, the TPL8601Q series is especially suitable for the off-board power supply through a long cable away from the main board in different automotive and industrial systems. The TPL8601Q series provides a thermal-enhanced ESOP8 package to enable sustained operation despite significant dissipation across the device. The TPL8601Q series is guaranteed to operate with an ambient temperature range from −40°C to +125°C.

Power Dissipation and Thermal Consideration During normal operation, the LDO junction temperature should meet the requirement in the Recommended Operating Conditions table. Use the below equations to calculate the power dissipation and estimate the junction temperature. The power dissipation can be calculated using the Equation 1. PD = VIN − VOUT × IOUT + VIN × IGND (1) The junction temperature can be estimated using the Equation 2. θJA is the junction-to-ambient thermal resistance. TJ = TA + PD × θJA (2) TPL8601Q 42-V/150-mA High-Precision Voltage-Tracking Low-Dropout Linear Regulator www.3peak.com 14 / 20 DA20250305A0

  • Both input capacitors and output capacitors must be placed to the device pins as close as possible, and the 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. Layout Example The following figure shows a layout example of the TPL8601Q-ES1R-S. OUT NC GND GND VIN Power Ground IN EN NC ADJ VOUT GND NC
