Frequently Asked Questions
What is the dropout voltage of the TPS78401QWDRBRQ1?
The TPS78401QWDRBRQ1 features a typical dropout voltage of just 115 mV, with a maximum of 0.9V, making it an ultra-low-dropout (ULDO) regulator. This extremely low dropout allows the device to maintain regulation even when the input voltage is only slightly above the output voltage, maximizing efficiency in battery-powered and automotive low-voltage applications.
Is the TPS78401QWDRBRQ1 AEC-Q100 qualified for automotive use?
Yes, the TPS78401QWDRBRQ1 carries AEC-Q100 automotive qualification, as indicated by the 'Q1' suffix. It has a YTEOL (Years to End of Life) rating of 15 years, indicating long-term supply commitment for automotive design programs. This makes it suitable for use in automotive infotainment, ADAS, body control, and powertrain applications.
What input voltage range does the TPS78401QWDRBRQ1 support?
The TPS78401QWDRBRQ1 accepts input voltages from 1.65V minimum to 6V maximum, making it compatible with a wide range of power sources including Li-ion battery outputs, 3.3V and 5V system rails, and automotive battery management circuits. The wide input range enables flexible power architecture design in both automotive and industrial applications.
What package does the TPS78401QWDRBRQ1 use?
The TPS78401QWDRBRQ1 is housed in an 8-pin WSON (Small Outline No-lead) package, JESD-30 code S-PDSO-N8. This compact leadless package provides excellent thermal performance and a small PCB footprint, making it ideal for space-constrained automotive ECUs and compact power management modules where heat dissipation and board area are critical constraints.
Is the TPS78401QWDRBRQ1 output voltage adjustable?
Yes, the TPS78401QWDRBRQ1 has an adjustable output voltage configuration, allowing designers to set the output voltage using an external resistor divider. This flexibility enables a single LDO part to power multiple voltage rails across different designs, reducing inventory complexity and allowing customization for specific system requirements in automotive and industrial power management applications.
