Texas Instruments TLV70727PDQNR

Overview

TLV70727PDQNR from Texas Instruments is a 200-mA, low-noise, low-quiescent-current (25 µA) LDO regulator with 2.7 V fixed output voltage, 0.5% DC accuracy, and 70 dB PSRR at 100 Hz. It operates from 2.0 V to 5.5 V input and delivers stable regulation down to 0.1 µF output capacitance - enabling compact, cost-effective power supply designs for battery-powered RF subsystems.

For engineers reviewing the TLV70727PDQNR datasheet, TLV70727PDQNR pinout, TLV70727PDQNR application, or TLV70727PDQNR equivalent, key selection criteria include dropout voltage at 150 mA (220–270 mV), active pulldown resistance (120 Ω), shutdown current (1 µA), thermal shutdown/overcurrent protection, and compatibility with space-constrained 1-mm × 1-mm X2SON packaging.

Technical Context

The TLV70727PDQNR implements a PMOS pass transistor architecture with integrated bandgap reference, enabling ultra-low quiescent current (25 µA) while maintaining tight 0.5% output accuracy across –40°C to +125°C. Its enable threshold (VIH = 0.9 V) supports direct interfacing with low-voltage GPIOs.

Unlike standard TLV707 variants, the "P" suffix denotes an active pulldown circuit (120 Ω internal resistor) that discharges the output during shutdown - critical for preventing back-powering or latch-up in multi-rail portable systems. Stability is guaranteed with ≥0.1 µF effective output capacitance, accommodating high-bias-voltage ceramic dielectrics.

FAQ

What is the maximum input voltage rating for TLV70727PDQNR?

The absolute maximum input voltage for TLV70727PDQNR is 6.0 V, but the recommended operating range is 2.0 V to 5.5 V. Exceeding 5.5 V may trigger internal protection or reduce reliability; sustained operation above 6.0 V risks permanent damage per TI's Absolute Maximum Ratings table.

Does TLV70727PDQNR require an external pull-up resistor on the EN pin?

No, TLV70727PDQNR does not require an external pull-up on EN. The device powers up enabled when EN is left floating or tied to IN. However, for deterministic startup/shutdown control in noisy environments, a 100-kΩ pull-up to IN is recommended to ensure VIH ≥ 0.9 V.

Can TLV70727PDQNR operate with a 0.1 µF output capacitor in all conditions?

Yes - TLV70727PDQNR is explicitly characterized and guaranteed stable with ≥0.1 µF effective output capacitance, including derating due to DC bias and temperature. This applies across the full –40°C to +125°C junction range and 0–200 mA load, per TI's Electrical Characteristics and Typical Characteristics sections.

What is the purpose of the thermal pad on the TLV70727PDQNR DQN package?

The exposed thermal pad on the TLV70727PDQNR DQN package must be soldered to a PCB copper pour to achieve specified thermal performance: R_θJB = 159.4°C/W. Omitting pad connection increases junction temperature by >40°C at 200 mA, risking premature thermal shutdown or long-term reliability degradation.

How does the pulldown circuit in TLV70727PDQNR improve system-level safety?

The 120-Ω internal pulldown in TLV70727PDQNR rapidly discharges the 2.7 V output rail during shutdown - preventing back-powering of upstream regulators or unintended activation of downstream logic. This eliminates latch-up risk in multi-supply systems and satisfies IEC 62368-1 energy storage safety requirements for portable devices.
