Texas Instruments TLV70736PDQNT

Overview

TLV70736PDQNT from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise (45 µVRMS), fixed 3.6-V output LDO regulator in a 1-mm × 1-mm X2SON (DQN) package. It delivers ±0.5% DC accuracy, supports 0.1-µF minimum output capacitance, and features 70 dB PSRR at 100 Hz - optimized for power-sensitive portable RF systems including wearable electronics and wireless handsets.

For engineers reviewing the TLV70736PDQNT datasheet, TLV70736PDQNT pinout, TLV70736PDQNT application, or TLV70736PDQNT equivalent, key selection considerations include its active pulldown circuit (120-Ω), 1-µs startup time, thermal shutdown/overcurrent protection, and compatibility with low-bias-voltage GPIO enable signals (VIH = 0.9 V).

Technical Context

The TLV70736PDQNT implements a PMOS pass transistor architecture enabling ultra-low dropout voltage (e.g., 220 mV at 150 mA for 3.6-V output) and reverse-voltage blocking via intrinsic body diode. Its internal bandgap reference and error amplifier deliver tight regulation across –40°C to +125°C junction temperature.

Unlike standard TLV707 variants, the "P" suffix denotes integrated active pulldown logic that discharges the output during shutdown - critical for fast system power sequencing in battery-powered devices. The EN pin's 0.9-V VIH threshold allows direct interfacing with modern low-voltage I/Os without level-shifting.

FAQ

What is the maximum input voltage rating for TLV70736PDQNT?

The absolute maximum input voltage for TLV70736PDQNT is 6.0 V. Operation above this level risks permanent damage. For reliable performance, maintain VIN within the recommended range of 2.0 V to 5.5 V, especially when delivering 200 mA output current at 3.6 V.

Does TLV70736PDQNT require an external pull-down resistor on the OUT pin?

No. TLV70736PDQNT includes an integrated 120-Ω active pulldown circuit activated during shutdown (EN < 0.4 V), eliminating the need for external components. This feature ensures rapid discharge of output capacitance - critical for clean power sequencing in portable systems.

Can TLV70736PDQNT operate with a 0.1-µF output capacitor?

Yes. TLV70736PDQNT is explicitly characterized for stability with ≥0.1-µF effective output capacitance - including derated values under bias and temperature. This enables use of compact 0402-case ceramics, reducing solution size versus traditional 1-µF requirements.

What is the typical startup time of TLV70736PDQNT?

The typical startup time for TLV70736PDQNT is 100 µs - defined as the interval from EN rising above 0.9 V to VOUT reaching 98% of 3.6 V with 1.0-µF output capacitance and 150-mA load. This fast turn-on supports responsive power management in duty-cycled systems.

How does the EN pin interface with low-voltage microcontrollers?

TLV70736PDQNT's EN pin has a VIH(EN) threshold of just 0.9 V, allowing direct connection to 1.2-V or 1.8-V GPIO outputs without level shifters. This simplifies design integration with modern ultra-low-power MCUs and application processors used in portable electronics.
