Product details
Overview
TLV70212DBVR from Texas Instruments is a 1.2 V fixed-output, 300-mA low-dropout (LDO) linear regulator in SOT-23-5 package, featuring 2% output accuracy, 35 μA quiescent current, 260 mV dropout at 300 mA, and 68 dB PSRR at 1 kHz - designed for Li-ion–powered handheld devices requiring stable low-noise bias.
For engineers reviewing the TLV70212DBVR datasheet, TLV70212DBVR pinout, TLV70212DBVR application, or TLV70212DBVR equivalent, this page delivers verified electrical specs, thermal behavior, enable-controlled power sequencing, and ceramic-capacitor–stable operation down to 0.1 μF - all critical for battery-life–sensitive RF and portable logic rails.
Technical Context
The TLV70212DBVR uses a PMOS pass transistor architecture enabling ultra-low dropout and high PSRR without requiring external compensation. Its precision bandgap reference and error amplifier deliver ±2% DC accuracy across –40°C to +125°C junction temperature, with integrated undervoltage lockout (1.9 V) and thermal shutdown (165°C).
It operates in three functional modes - normal regulation, dropout (VIN < VOUT + VDO), and current limit (ICL = 320–860 mA) - with active pulldown only on TLV702P variants; the TLV70212DBVR lacks internal discharge but supports fast EN-controlled shutdown with 400 nA shutdown current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±2% over –40°C to +125°C; enables direct powering of low-voltage logic cores and RF ICs without external feedback. |
| Max Output Current | 300 mA continuous; sufficient for single-core microcontrollers, Bluetooth SoCs, and sensor hubs in space-constrained designs. |
| Dropout Voltage | 260 mV at 300 mA; allows regulation from 1.46 V input - critical for extending runtime in single-cell Li-ion (2.7–4.2 V) systems. |
| Quiescent Current | 35 μA typical at no load; minimizes standby drain in always-on wake-up circuits and IoT edge nodes. |
| PSRR | 68 dB at 1 kHz; suppresses switching noise from adjacent DC/DC converters feeding mixed-signal subsystems. |
| Stability Capacitance | Stable with ≥0.1 μF ceramic output capacitor; enables use of small 0402/0603 X5R/X7R caps, reducing BOM cost and PCB area. |
| Enable Threshold | EN high = ≥0.9 V, low = ≤0.4 V; supports direct interfacing with 1.8 V GPIOs and open-drain sequencers without level shifters. |
Pinout & Package
SOT-23-5 (DBV) package: 2.90 mm × 1.60 mm body, 0.95 mm height, surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input voltage supply | Accepts 2 V to 5.5 V; requires 0.1–1 μF ceramic capacitor to GND for transient immunity and stability. |
| 2 - GND | Power ground reference | Single-point connection for VIN and VOUT return paths; must tie to low-impedance system ground plane. |
| 3 - EN | Active-high enable control | Pulls regulator ON above 0.9 V; reduces ground current to 400 nA in shutdown - ideal for firmware-controlled power gating. |
| 4 - NC | No-connect terminal | Internally unconnected; may be tied to GND to improve thermal dissipation in high-power-density layouts. |
| 5 - OUT | Regulated output | Delivers 1.2 V ±2%; requires 0.1–1 μF ceramic cap to GND; output impedance <100 mΩ ensures clean rail for analog/RF loads. |
Key Features
| Feature | Design Value |
|---|---|
| Low IQ operation | 35 μA quiescent current enables >1-year battery life in coin-cell–powered sensors with periodic wake-up. |
| High PSRR at 1 kHz | 68 dB rejection of ripple from upstream buck converters preserves signal integrity in ADC reference and PLL supply rails. |
| Ultra-low minimum capacitance | 0.1 μF effective output capacitance requirement allows use of compact, bias-stable ceramics - no tantalum or electrolytic needed. |
| Thermal & current protection | Integrated thermal shutdown (165°C trip) and current limit (320–860 mA) prevent damage during short-circuit or overload events. |
| Wide input voltage range | 2 V to 5.5 V input supports direct connection to USB, Li-ion, and multi-cell alkaline sources without pre-regulation. |
Applications
| Wireless Handset Power Rail | Bluetooth Low Energy Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A0512DBVR | Lower IQ (25 μA), same 1.2 V output, but higher dropout (300 mV @ 300 mA); WSON-4 package only. | Lacks EN pin - unsuitable for sequenced power-down; better for always-on ultra-low-IQ roles. | Select when absolute lowest standby current is prioritized over enable control and dropout margin. |
| MCP1700T-1202E/TT | Higher accuracy (±0.4%), but lower max current (250 mA); 6 μA IQ, SOT-23-3 (no EN pin). | No enable function; limited to fixed 1.2 V with tighter tolerance - best for non-sequenced, low-current analog rails. | Choose for precision analog bias where EN is unnecessary and load stays below 250 mA. |
Compared with TPS7A0512DBVR and MCP1700T-1202E/TT, the TLV70212DBVR uniquely balances 300 mA drive capability, EN control, 260 mV dropout, and 35 μA IQ - making it optimal for dynamically managed, battery-constrained digital subsystems requiring both performance and flexibility.

FAQ
What is the maximum input voltage rating for TLV70212DBVR?
The TLV70212DBVR has an absolute maximum input voltage of 6.0 V, with recommended operating range from 2.0 V to 5.5 V. Exceeding 6.0 V risks permanent damage; operation above 5.5 V is outside specification and may degrade long-term reliability even if within absolute max limits.
Does TLV70212DBVR include an internal discharge path for the output capacitor?
No, the TLV70212DBVR does not include an internal active pulldown circuit. That feature is exclusive to the TLV702P variant (e.g., TLV70212PDBVR). When TLV70212DBVR is disabled via EN, the output floats and relies on external bleed resistors or load leakage for discharge.
Can TLV70212DBVR operate stably with a 0.1 μF output capacitor?
Yes - the TLV70212DBVR is explicitly characterized and guaranteed stable with an effective output capacitance of ≥0.1 μF, including bias- and temperature-derated values. This enables use of compact 0402/0603 X5R/X7R ceramics without compromising phase margin.
What is the thermal shutdown threshold for TLV70212DBVR?
The TLV70212DBVR triggers thermal shutdown at approximately 165°C junction temperature and resets at ~145°C. This hysteresis prevents oscillation during marginal thermal conditions and protects the device during sustained overload or poor PCB heatsinking.
Is TLV70212DBVR pin-compatible with other TLV702xx variants in SOT-23-5?
Yes - all TLV702xx DBV (SOT-23-5) variants share identical pinout: Pin 1 = IN, Pin 2 = GND, Pin 3 = EN, Pin 4 = NC, Pin 5 = OUT. Output voltage is set internally; swapping TLV70212DBVR with TLV70218DBVR requires no PCB change, only firmware or system-level validation of voltage tolerance.
