Texas Instruments TLV70715PDQNR

Overview

TLV70715PDQNR from Texas Instruments is a 200-mA, low-noise, low-quiescent-current (25 µA) LDO regulator with 0.5% output accuracy and 1.5-V fixed output voltage, housed in a 1-mm × 1-mm DQN (X2SON-4) package. It delivers stable regulation down to 0.1-µF output capacitance and features active pulldown (120-Ω), thermal shutdown, and overcurrent protection - optimized for space-constrained portable RF systems such as wearable sensors and Bluetooth audio modules.

For engineers reviewing the TLV70715PDQNR datasheet, TLV70715PDQNR pinout, TLV70715PDQNR application, or TLV70715PDQNR equivalent, key selection criteria include dropout voltage at 150 mA (220–270 mV for 1.5-V output), PSRR (70 dB @ 100 Hz, 50 dB @ 1 MHz), shutdown current (1 µA), EN logic thresholds (VIH = 0.9 V, VIL = 0.4 V), and compatibility with ultra-small ceramic capacitors under bias and temperature derating.

Technical Context

The TLV70715PDQNR implements a PMOS pass transistor architecture enabling low dropout and fast load transient response (<100 µs start-up time). Its internal bandgap reference and error amplifier maintain ±1.5% DC accuracy across –40°C to +125°C junction temperature and support zero-load regulation.

Unlike standard TLV707 variants, the "P" suffix denotes integrated active pulldown circuitry that discharges the output via a 120-Ω internal resistor during shutdown - critical for preventing floating nodes in multi-rail power sequencing and reducing system-level wake-up latency.

FAQ

What is the maximum input voltage rating for TLV70715PDQNR?

The absolute maximum input voltage for TLV70715PDQNR is 6.0 V. Operation above this level risks permanent damage. For reliable continuous operation, TI specifies a recommended input range of 2.0 V to 5.5 V - ensuring proper regulation, thermal margin, and PSRR performance across temperature and load conditions. Always include input transient protection if the source may exceed 6.0 V.

Does TLV70715PDQNR require an external pull-down resistor on the OUT pin?

No. TLV70715PDQNR 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 deterministic power sequencing in multi-rail systems - and reduces BOM count and PCB area versus standard LDOs.

Can TLV70715PDQNR operate with zero load current?

Yes. TLV70715PDQNR regulates to its specified 1.5-V output accuracy even with 0 mA load current, confirmed across –40°C to +125°C junction temperature. This zero-load capability supports standby modes in always-on sensors and simplifies design by removing minimum load requirements common in older LDO architectures.

What is the minimum output capacitance required for stability with TLV70715PDQNR?

TLV70715PDQNR is stable with an effective output capacitance of ≥0.1 µF - defined as the capacitance value under actual operating bias voltage and temperature. This allows use of compact 0402 X5R/X7R ceramics (e.g., 0.22 µF rated) that retain ≥0.1 µF after derating, unlike legacy LDOs requiring ≥1 µF and larger footprints.

How does the EN pin logic threshold affect compatibility with modern MCUs?

TLV70715PDQNR's EN pin has VIH = 0.9 V (min) and VIL = 0.4 V (max), enabling direct interfacing with low-voltage GPIOs (e.g., 1.8-V or 1.2-V I/O domains) found in Cortex-M0+/M33 microcontrollers and application processors. This eliminates level-shifting requirements and simplifies power-control firmware implementation compared to LDOs needing ≥1.2-V enable thresholds.
