Product details
Overview
TLV70237DBVT from Texas Instruments is a 3.7 V fixed-output, 300-mA low-dropout (LDO) linear regulator in SOT-23-5 package, featuring 2% output accuracy, 35 μA quiescent current, and 260 mV dropout at 300 mA load - designed for Li-ion battery-powered handheld devices requiring stable low-noise supply under light-to-moderate load.
For engineers reviewing the TLV70237DBVT datasheet, TLV70237DBVT pinout, TLV70237DBVT application, or TLV70237DBVT equivalent, this page delivers verified electrical specs, thermal behavior, enable-controlled power sequencing, and design-critical capacitor stability guidance for space-constrained portable RF systems.
Technical Context
The TLV70237DBVT uses a PMOS pass transistor to achieve low dropout and maintain regulation down to 260 mV headroom at full 300 mA load. Its precision bandgap reference and error amplifier deliver ±2% DC accuracy across –40°C to +125°C junction temperature.
It integrates active high-enable logic (VEN(H) = 0.9 V, VEN(L) = 0.4 V), thermal shutdown (165°C trip), overcurrent protection (320–860 mA limit), and undervoltage lockout (1.9 V). Unlike the TLV702P variant, it lacks internal active pulldown; output discharge requires external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.7 V ±2% - ensures stable rail for 3.3 V–3.8 V logic or RF ICs without external feedback network. |
| Max Output Current | 300 mA continuous - supports moderate-power microcontrollers, Bluetooth SoCs, or sensor hubs. |
| Dropout Voltage | 260 mV at 300 mA - enables operation down to VIN = 3.96 V, extending usable battery life in single-cell Li-ion systems. |
| Quiescent Current | 35 μA typical at no load - minimizes standby power loss in always-on subsystems like wake-on-RF or real-time clocks. |
| PSRR | 68 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters feeding sensitive analog/RF blocks. |
| Stability Capacitance | 0.1 μF minimum ceramic - allows use of small, low-cost X5R/X7R capacitors even with voltage/temperature derating. |
| Enable Threshold | 0.9 V (high), 0.4 V (low) - compatible with 1.8 V GPIOs and supports clean power sequencing in multi-rail systems. |
Pinout & Package
SOT-23-5 (DBV) package: 2.90 mm × 1.60 mm body, surface-mount, thermally enhanced with exposed pad (not electrically connected in DBV variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input voltage supply | Accepts 2 V to 5.5 V input; requires ≥0.1 μF ceramic decoupling close to pin for transient immunity and PSRR optimization. |
| 2 - GND | Power ground reference | Single-point connection for IN and OUT return paths; critical for noise isolation and thermal performance in layout. |
| 3 - EN | Enable control input | Active-high logic; drives device ON above 0.9 V, OFF below 0.4 V; draws only 0.04 μA leakage when asserted. |
| 4 - NC | No connection | Internally unconnected; may be tied to GND to improve thermal dissipation but has no electrical function. |
| 5 - OUT | Regulated output | Delivers 3.7 V ±2%; requires ≥0.1 μF ceramic capacitor directly between OUT and GND for stability and load transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Low IQ operation | 35 μA quiescent current enables >1-year battery life in coin-cell–powered IoT sensors with periodic wake-up. |
| High PSRR at 1 kHz | 68 dB rejection of ripple from switching regulators - preserves signal integrity in RF front-end bias rails. |
| Ultra-low minimum capacitance | Stable with 0.1 μF effective output capacitance - reduces BOM cost and PCB area vs. legacy LDOs requiring ≥2.2 μF. |
| Thermal & current protection | Integrated shutdown at 165°C and current limit (320–860 mA) prevent damage during short-circuit or overload events. |
| Wide input range | 2 V to 5.5 V operation supports direct connection to USB, Li-ion, or boosted 3.3 V supplies without pre-regulation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLS850F0TESK | 500 mA rated, 45 μA IQ, integrated watchdog timer and reset generator; requires external 10 nF bypass cap on VREF. | Targeted at automotive ASIL-B systems; includes fail-safe monitoring not present in TLV70237DBVT. | Select when functional safety features (reset, window watchdog) and higher current are required; not drop-in due to different pinout and enable logic. |
| MCP1700T-3702E/TT | 250 mA max, 1.6 μA IQ, 170 mV dropout at 250 mA; no enable pin, fixed 3.7 V output in SOT-23-3. | Ultra-low-power always-on applications (e.g., battery-backed SRAM); lacks enable control and thermal shutdown. | Select when minimal IQ dominates design priority and enable/shutdown functionality is unnecessary; incompatible pin count and missing protection features. |

FAQ
What is the maximum input voltage rating for TLV70237DBVT?
The TLV70237DBVT has an absolute maximum input voltage of 6.0 V. Operation beyond this risks permanent damage. The recommended operating range is 2 V to 5.5 V, ensuring optimal regulation, thermal margin, and PSRR performance across temperature and load conditions. Exceeding 5.5 V may trigger internal UVLO or degrade long-term reliability.
Does TLV70237DBVT include an enable pin, and what are its voltage thresholds?
Yes, TLV70237DBVT includes an active-high enable (EN) pin. It turns ON when EN voltage exceeds 0.9 V (typical) and enters shutdown when EN falls below 0.4 V (typical). Shutdown reduces ground current to ≤2 μA, preserving battery life. The EN pin draws only 0.04 μA leakage when asserted, supporting direct connection to low-drive GPIOs.
Can TLV70237DBVT operate stably with a 0.1 μF output capacitor?
Yes, TLV70237DBVT is explicitly characterized and guaranteed stable with an effective output capacitance of 0.1 μF or greater - including X5R/X7R ceramics under bias and temperature derating. This enables use of compact 0402- or 0603-size capacitors, reducing PCB area and BOM cost versus legacy LDOs requiring ≥2.2 μF.
What is the dropout voltage of TLV70237DBVT at 300 mA load?
The dropout voltage of TLV70237DBVT is 260 mV (typical) at 300 mA output current and 25°C junction temperature. At full load, this means the device regulates properly down to VIN = 3.96 V. Dropout increases with temperature and decreases slightly at lighter loads - e.g., 37 mV at 50 mA per datasheet characterization.
Is TLV70237DBVT pin-compatible with other variants in the TLV702 family?
Yes, TLV70237DBVT shares identical SOT-23-5 (DBV) pinout with all TLV702xxDBVT variants (e.g., TLV70233DBVT, TLV70245DBVT). Pin 1 = IN, Pin 2 = GND, Pin 3 = EN, Pin 4 = NC, Pin 5 = OUT. Output voltage is set internally; no external resistors are needed. This allows voltage-scaling flexibility within the same footprint during design iteration.
