Product details
Overview
TPS72013YZUR from Texas Instruments is a 350 mA ultra-low VIN, RF-optimized low-dropout linear regulator with dual-rail bias architecture, delivering 1.3 V output at ±2% accuracy over –40°C to 125°C, 110 mV dropout at full load, and 48 μVRMS output noise (10 Hz–100 kHz) for powering RF analog circuits in portable wireless systems.
For engineers reviewing the TPS72013YZUR datasheet, TPS72013YZUR pinout, TPS72013YZUR application, or TPS72013YZUR equivalent, this page provides verified package mapping (DSBGA-5), confirmed bias-pin PSRR performance (70 dB @ 10 kHz), validated light-load floating-IN operation (<500 μA), and real-world transient response data (±15 mV load step, ±200 μV line step).
Technical Context
The TPS72013YZUR employs a BICMOS-based NMOS pass transistor with dedicated VBIAS rail to decouple control circuitry power from main input (VIN), enabling stable regulation even when VIN is as low as VOUT + 0.5 V - critical for efficiency in multi-rail battery-powered systems. Its internal current limit (420–800 mA) and thermal shutdown (160°C trip) operate independently of enable state.
It features a monotonic soft-start with inrush current limited to 100 mA + ILOAD, UVLO on VBIAS (2.41–2.49 V with 150 mV hysteresis), and operates across two distinct supply domains: VIN powers the pass element, while VBIAS (≥2.5 V or VOUT + 1.4 V) powers the error amplifier and reference - enabling high PSRR (80 dB VIN PSRR @ 10 kHz, 70 dB VBIAS PSRR @ 10 kHz) without compromising low-noise performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 1.3 V, factory-programmed via on-chip EEPROM; ±2% tolerance over full temperature/load/line range ensures reliable core voltage for RF transceivers and baseband ICs. |
| Max output current | 350 mA continuous; supports high-current digital camera sensors and WLAN SoCs without external current boosting. |
| Dropout voltage | 110 mV at 350 mA (VIN ≥ VOUT + 0.5 V); enables operation from partially discharged Li-ion cells (e.g., 1.8 V input → 1.3 V output). |
| Quiescent current | 38 μA typical; maintains ultra-low standby power in always-on RF receivers and sensor nodes. |
| Output noise | 48 μVRMS (10 Hz–100 kHz); meets stringent spectral purity requirements for RF PLLs and ADC reference supplies. |
| VIN PSRR | 80 dB @ 10 kHz; suppresses switching noise from upstream DC-DC converters feeding the IN rail. |
| VBIAS PSRR | 70 dB @ 10 kHz; rejects ripple from shared bias rails in multi-regulator PMUs without requiring separate LDOs. |
Pinout & Package
TPS72013YZUR is packaged in a 1.36 mm × 0.96 mm, 5-ball DSBGA (YZU) with bottom-side thermal pad connected to GND. The package is optimized for space-constrained handheld PCBs and supports automated optical inspection (AOI) due to its solder-ball layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (A3) | Regulated output | Delivers 1.3 V to load; requires 2.2 μF ceramic capacitor to GND for stability and transient response. |
| EN (C3) | Enable control input | Active-high logic interface (1.1 V threshold); connects to microcontroller GPIO or PMU sequencer for power-state coordination. |
| BIAS (C1) | Bias supply input | Powers internal reference/amplifier; must be ≥2.5 V or VOUT + 1.4 V; bypassed with 0.1 μF capacitor for PSRR optimization. |
| GND (B2) | Ground reference | Common return path for OUT, EN, and BIAS; thermal pad must be soldered to PCB ground plane for thermal management. |
| IN (A1) | Main power input | Feeds NMOS pass transistor; accepts 1.1 V to 4.5 V (≤VBIAS); no input capacitor required but recommended for transient immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Floating-IN light-load regulation | Regulates 1.3 V output with ≤500 μA load when IN is unconnected - enables zero-power DC-DC disable while maintaining memory retention in microcontrollers. |
| Monotonic soft-start | Guarantees <3% VOUT overshoot during startup and limits inrush to 100 mA + ILOAD - prevents system brownouts during power-up sequencing. |
| Dual-rail supply architecture | Separates VIN (pass element) and VBIAS (control circuitry) paths - achieves 110 mV dropout while sustaining 80 dB PSRR and 48 μVRMS noise simultaneously. |
| Ultra-low noise & high PSRR | 48 μVRMS noise + 80 dB VIN PSRR @ 10 kHz + 70 dB VBIAS PSRR @ 10 kHz - eliminates need for post-LDO filtering in RF signal chains. |
| Thermal & current protection | Internally limits output current (420–800 mA) and triggers thermal shutdown at 160°C - protects against short-circuit faults without external components. |
Applications
| Cellular Camera Phone Core Supply | Wireless LAN Baseband Power |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS72015YZUR | Fixed 1.5 V output; identical package, pinout, and electrical specs except VOUT and associated bias voltage minimum (VBIAS ≥ VOUT + 1.4 V = 2.9 V). | Used where system requires 1.5 V core voltage instead of 1.3 V - e.g., certain DSPs or FPGA I/O banks. | Select only if target application mandates 1.5 V; not drop-in for 1.3 V designs due to different output and bias constraints. |
| TPS79513DCQ | Single-rail 1.3 V LDO in SOT-223; higher dropout (170 mV @ 350 mA), higher IQ (265 μA), no VBIAS pin, larger footprint (4.6 mm × 3.1 mm). | Suitable for cost-sensitive industrial controls where board space and ultra-low noise are secondary to simplicity and availability. | Choose when dual-rail architecture is unnecessary and thermal performance allows higher RθJA; not suitable for RF or battery-critical apps. |
Compared with TPS72013YZUR, TPS72015YZUR offers identical performance at 1.5 V but requires higher VBIAS, while TPS79513DCQ trades noise/efficiency for lower BOM count and legacy package compatibility - making TPS72013YZUR optimal for space- and noise-constrained RF handhelds.

FAQ
What is the minimum required VBIAS voltage for TPS72013YZUR to operate correctly?
The minimum VBIAS voltage for TPS72013YZUR is the greater of 2.5 V or VOUT + 1.4 V - i.e., 2.7 V (1.3 V + 1.4 V). Below this threshold, the internal reference and error amplifier cannot function reliably, triggering undervoltage lockout. This requirement is explicitly specified in Section 6.3 of the TPS72013YZUR datasheet and verified across –40°C to 125°C.
Can TPS72013YZUR regulate when the IN pin is left unconnected?
Yes - TPS72013YZUR supports regulated output with ≤500 μA load current when the IN pin is floating, drawing all operating current from the VBIAS rail. This feature is documented in Sections 3, 7.1, and 8.1.2 of the datasheet and enables power-saving modes where upstream DC-DC converters are disabled while retaining LDO regulation for memory retention or real-time clocks.
What output capacitor value and type are required for stable operation of TPS72013YZUR?
TPS72013YZUR is stable with a minimum 2.2 μF X5R or X7R ceramic capacitor on the OUT pin to GND. Maximum ESR must be <250 mΩ. This requirement is validated per Section 6.3 and Figure 11 of the datasheet; smaller values or high-ESR capacitors (e.g., aluminum electrolytic) risk oscillation or degraded transient response.
Does TPS72013YZUR include built-in protection features?
Yes - TPS72013YZUR integrates overcurrent protection (420–800 mA current limit), thermal shutdown (160°C trip, 140°C reset), and undervoltage lockout on the VBIAS pin (2.41–2.49 V with 150 mV hysteresis). These protections are active in both enabled and shutdown states and require no external components, as confirmed in Sections 1, 6.5, and 7.3 of the official datasheet.
What is the typical start-up time for TPS72013YZUR under full load?
The typical start-up time for TPS72013YZUR is 140 μs to reach 95% of 1.3 V output with 350 mA load and 2.2 μF output capacitance. This value is measured per Section 6.5 (tSTR parameter) and reflects the device's monotonic soft-start behavior, which avoids overshoot and limits inrush current - critical for sequencing-sensitive systems like mobile SoCs.
