Product details
Overview
TLV70213DBVT from Texas Instruments is a 300-mA, low-quiescent-current, low-dropout linear regulator with fixed 1.3-V output, 2% DC accuracy, 35-μA quiescent current, and 260-mV dropout at 300 mA - designed for Li-ion battery-powered handheld devices requiring stable, low-noise power under light-to-moderate load.
For engineers reviewing the TLV70213DBVT datasheet, TLV70213DBVT pinout, TLV70213DBVT application, or TLV70213DBVT equivalent, this page delivers verified package mapping (SOT-23-5), confirmed thermal shutdown/overcurrent protection, PSRR of 68 dB at 1 kHz, stability with ≥0.1-μF ceramic output capacitance, and real-world transient performance data for portable RF and wireless systems.
Technical Context
The TLV70213DBVT uses a PMOS pass transistor to achieve low dropout and maintains regulation down to 260 mV headroom at full 300-mA load. Its precision bandgap reference and error amplifier deliver ±2% output accuracy across –40°C to +125°C junction temperature.
It features active-high enable (VEN(high) = 0.9 V), 1-μA shutdown current, undervoltage lockout (UVLO = 1.9 V), and integrated thermal shutdown (trip = 165°C, reset = 145°C). The device is stable with output capacitors as small as 0.1 μF, enabling compact, cost-effective designs using X5R/X7R ceramics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 1.3 V - eliminates external feedback network; supports low-voltage logic rails like I/O interfaces in Bluetooth/WLAN ICs. |
| Max output current | 300 mA - sufficient for powering baseband processors, RF transceivers, or sensor hubs in compact portable devices. |
| Quiescent current | 35 μA - enables >1-year battery life in always-on IoT sensors operating from single Li-ion cells. |
| Dropout voltage | 260 mV at 300 mA - allows operation down to VIN = 1.56 V, extending usable battery range beyond typical LDO limits. |
| PSRR | 68 dB at 1 kHz - suppresses switching noise from adjacent DC/DC converters, critical for RF-sensitive analog circuits. |
| Output accuracy | ±2% over –40°C to +125°C - ensures reliable logic-level compatibility without margining for drift in industrial-grade handhelds. |
| Stability capacitance | ≥0.1 μF ceramic - permits use of 0402/0603-size capacitors, reducing PCB area by up to 50% vs. legacy 1-μF requirements. |
Pinout & Package
TLV70213DBVT is packaged in a 5-pin SOT-23 (DBV) with 2.90 mm × 1.60 mm body size and standard lead pitch. Thermal performance is characterized by RθJA = 249.2°C/W (JEDEC high-K board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input supply connection | Accepts 2–5.5 V input; requires ≥0.1-μF ceramic capacitor to GND for stability and transient suppression. |
| GND (Pin 2) | Power ground reference | Single-point return path for IN and OUT; must connect directly to low-impedance ground plane to minimize noise coupling. |
| EN (Pin 3) | Enable control input | Active-high logic: ≥0.9 V enables regulation; ≤0.4 V disables output and reduces IQ to 1 μA (no pulldown - TLV702P only). |
| NC (Pin 4) | No-connect terminal | Internally unconnected; may be tied to GND to improve thermal dissipation in high-power-density layouts. |
| OUT (Pin 5) | Regulated output | Delivers 1.3 V ±2%; requires ≥0.1-μF ceramic capacitor to GND placed adjacent to pin for optimal PSRR and load transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout voltage | 260 mV at 300 mA enables extended battery runtime in 1.5-V–2.0-V input ranges common in partially discharged Li-ion cells. |
| Ultra-low quiescent current | 35 μA supports multi-year operation in battery-backed real-time clocks, wearables, and remote sensors without compromising regulation. |
| High PSRR | 68 dB at 1 kHz rejects ripple from noisy switchers, preserving signal integrity in RF front-end bias supplies and ADC reference paths. |
| Thermal & current protection | Integrated shutdown at 165°C and current limit ≥320 mA prevent damage during short-circuit or overload events without external circuitry. |
| Minimal output capacitance | Stable with 0.1 μF ceramic allows use of smaller, lower-cost capacitors - critical for space-constrained mobile PCBs and cost-sensitive consumer designs. |

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 rating, higher IQ (70 μA), adjustable output (1.0–5.0 V), TO-252-5 package | Targeted at automotive body electronics with AEC-Q100 qualification; lacks 0.1-μF stability guarantee | Select when higher current, automotive qualification, or output adjustability outweighs footprint and quiescent current constraints. |
| MCP1703T-1302E/MB | 250-mA rating, 4 μA IQ, 600-mV dropout at 250 mA, SOT-23-5 package | Optimized for ultra-low-power applications but exhibits degraded PSRR (55 dB @ 1 kHz) and requires ≥1-μF output cap | Choose only if sub-10-μA standby current is mandatory and PSRR/transient performance are secondary concerns. |
Compared with TLS850F0TESK and MCP1703T-1302E/MB, TLV70213DBVT offers superior balance of low dropout (260 mV), ultra-low IQ (35 μA), high PSRR (68 dB), and minimal 0.1-μF stability - making it the preferred choice for space- and battery-limited portable RF systems where all four parameters are simultaneously critical.

FAQ
What is the maximum input voltage rating for TLV70213DBVT?
The absolute maximum input voltage for TLV70213DBVT is 6.0 V, as specified in the Absolute Maximum Ratings table. Operation above this level risks permanent damage. For reliable continuous operation, the recommended input range is 2.0 V to 5.5 V per the Recommended Operating Conditions section - ensuring proper regulation, thermal safety, and PSRR performance across the full temperature range.
Does TLV70213DBVT include an active output pulldown circuit?
No, TLV70213DBVT does not include an active pulldown circuit. That feature is exclusive to the TLV702P variant (e.g., TLV70213PDBVR), which integrates a 120-Ω internal discharge resistor on the OUT pin during shutdown. TLV70213DBVT enters low-current shutdown (≤1 μA) when EN < 0.4 V but leaves the output floating - external pulldown is required if rapid discharge is needed.
Can TLV70213DBVT operate stably with a 0.1-μF output capacitor?
Yes, TLV70213DBVT is explicitly characterized and guaranteed stable with an effective output capacitance of ≥0.1 μF, provided it is a ceramic type (X5R/X7R) and meets ESR < 200 mΩ. This capability is validated across –40°C to +125°C and enables use of miniature 0402/0603 capacitors - a key differentiator versus legacy LDOs requiring ≥1-μF minimum.
What is the thermal shutdown behavior of TLV70213DBVT?
TLV70213DBVT activates thermal shutdown at approximately 165°C junction temperature and resets regulation when the die cools to ~145°C. This hysteresis prevents oscillation during marginal thermal conditions. Under sustained overload, the device cycles between shutdown and regulation - a protective mechanism that avoids permanent damage but indicates inadequate heatsinking or excessive power dissipation in the final design.
Is TLV70213DBVT pin-compatible with other TLV702xx variants in SOT-23-5?
Yes, all TLV702xx devices in the DBV (SOT-23-5) package share identical pinout: Pin 1 = IN, Pin 2 = GND, Pin 3 = EN, Pin 4 = NC, Pin 5 = OUT. This allows direct substitution between fixed-output versions (e.g., TLV70213DBVT, TLV70218DBVT) without PCB changes - provided input/output voltage ranges and load requirements remain compatible.
