Product details
Overview
TPS720132YZUR from Texas Instruments is a 350 mA ultra-low VIN, RF-optimized low-dropout linear regulator with dual-rail bias architecture, delivering 1.32 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) - used in cellular camera phone core power rails where low noise and fast transient response are critical.
For engineers reviewing the TPS720132YZUR datasheet, TPS720132YZUR pinout, TPS720132YZUR application, or TPS720132YZUR equivalent, key selection criteria include its dual-rail (VIN/VBIAS) operation, 38 μA quiescent current, monotonic soft-start with 100 mA + ILOAD inrush limiting, and stability with 2.2 μF ceramic output capacitance in space-constrained handheld designs.
Technical Context
The TPS720132YZUR employs an NMOS pass transistor with separate VIN (main power path) and VBIAS (control circuit supply) rails, enabling high efficiency when VIN is as low as VOUT + 0.5 V while VBIAS ≥ VOUT + 1.4 V or 2.5 V. Its advanced BICMOS process delivers 110 mV dropout at 350 mA and supports IN-pin floating operation for light-load regulation via VBIAS only.
It features integrated undervoltage lockout (UVLO) on VBIAS (2.45 V nominal, 150 mV hysteresis), thermal shutdown (160°C trip), overcurrent protection, and 80 dB PSRR at 10 kHz on VIN and 70 dB on VBIAS - all specified across –40°C to 125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | 1.32 V factory-programmed, ±2% accuracy over load/line/temp (–40°C to 125°C) |
| Max output current | 350 mA continuous; internal current limit 420–800 mA depending on conditions |
| Dropout voltage | 110 mV at 350 mA (VIN-to-VOUT), enabling operation with minimal headroom |
| Quiescent current | 38 μA typical, enabling battery-sensitive portable applications |
| Output noise | 48 μVRMS (10 Hz–100 kHz), suitable for RF and analog signal chain power |
| PSRR (VIN) | 80 dB at 10 kHz, 70 dB at 100 kHz - suppresses switching noise from upstream DC-DC converters |
| Start-up time | 140 μs to 95% VOUT(NOM) with 2.2 μF COUT, supporting fast system wake-up |
Pinout & Package
TPS720132YZUR is packaged in a 1.36 mm × 0.96 mm, 5-ball DSBGA (YZU) package with exposed substrate. The package is optimized for ultra-compact handheld PCB layouts and requires no thermal pad connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (A3) | Regulated output | Delivers 1.32 V to load; requires 2.2 μF ceramic capacitor to GND for stability and transient response |
| NC (-) | No connection | Unbonded die pad; must be left floating or tied to GND per layout guidelines |
| EN (C3) | Enable control input | Active-high logic (1.1 V threshold); connects to microcontroller GPIO or upstream DC-DC enable for coordinated power sequencing |
| BIAS (C1) | Bias supply rail | Powers internal control circuitry; must be ≥ VOUT + 1.4 V or 2.5 V (whichever greater); enables IN-pin floating light-load operation |
| GND (B2) | Ground reference | Common return for IN, BIAS, OUT, and EN; requires low-impedance PCB plane connection |
| IN (A1) | Main input power path | Accepts 1.1 V to 4.5 V (≤ VBIAS); can be fed by efficient DC-DC converter to maximize overall system efficiency |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail architecture (VIN + VBIAS) | Enables use of low-voltage DC-DC for VIN while maintaining high-efficiency control via higher VBIAS rail |
| IN-pin floating light-load regulation | Sustains 1.32 V output with ≤500 μA load drawn solely from VBIAS - ideal for standby mode with DC-DC disabled |
| Monotonic soft-start | Limits VIN inrush to 100 mA + ILOAD and caps VOUT overshoot to ≤3%, preventing system reset during power-up |
| Ultra-low noise & high PSRR | 48 μVRMS noise and 80 dB VIN PSRR up to 10 kHz - preserves signal integrity in RF transceivers and ADC/DAC supplies |
| Full automotive-grade temp range | Specified from –40°C to 125°C junction temperature with guaranteed performance across extremes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS72012YZUR | Fixed 1.2 V output (vs. 1.32 V); identical package, pinout, and electrical specs otherwise | Used where system SoC requires 1.2 V core voltage instead of 1.32 V | Select when target load voltage matches 1.2 V; drop-in replacement with no layout change |
| TPS79513QDBVRQ1 | Automotive-grade (AEC-Q100), 1.3 V output, 250 mA max, SOT-23-5 package, no VBIAS pin | Designed for automotive infotainment and ADAS; lacks dual-rail efficiency and IN-floating capability | Choose only for automotive qualification needs; not suitable for space-constrained or ultra-low-IQ portable designs |
Compared with TPS720132YZUR, TPS72012YZUR offers identical performance at 1.2 V for different core voltage requirements, while TPS79513QDBVRQ1 provides AEC-Q100 compliance but sacrifices dual-rail efficiency, light-load floating operation, and 350 mA capability - making it unsuitable for high-performance portable RF systems.

FAQ
What is the exact output voltage of the TPS720132YZUR?
The TPS720132YZUR is factory-programmed to deliver a precise 1.32 V output voltage. Its accuracy is ±2% over full operating conditions - including load (0–350 mA), line (VIN = VOUT + 0.5 V to 4.5 V), temperature (–40°C to 125°C), and process variation - as verified in the SBVS100E datasheet Section 6.5.
Can the TPS720132YZUR operate with the IN pin disconnected?
Yes, the TPS720132YZUR supports IN-pin floating operation under light loads (≤500 μA), sourcing regulated 1.32 V output exclusively from the VBIAS rail. This feature is explicitly documented in Sections 3, 7.1, and 8.1.2 of the datasheet and enables ultra-low-power standby modes when upstream DC-DC converters are disabled.
What is the minimum required output capacitance for stability of the TPS720132YZUR?
The TPS720132YZUR is stable with a minimum 2.2 μF ceramic output capacitor (X5R or X7R dielectric), as confirmed in Sections 3, 6.3, and 8.1.1 of the SBVS100E datasheet. Using smaller values risks instability and degraded transient response; maximum ESR must remain below 250 mΩ.
Does the TPS720132YZUR require an input capacitor on the IN pin?
No, the TPS720132YZUR does not require an input capacitor for stability on the IN pin. However, TI recommends a 0.1–1 μF low-ESR ceramic capacitor near the IN pin to improve transient response and noise rejection - especially when source impedance is high or fast load steps occur, per Section 8.1.1 of the datasheet.
What is the purpose of the BIAS pin on the TPS720132YZUR?
The BIAS pin on the TPS720132YZUR powers the internal control circuitry independently of the main VIN rail. It must be supplied with ≥ VOUT + 1.4 V (or 2.5 V, whichever is greater) and enables both high PSRR (70 dB at 10 kHz) and IN-pin floating operation. This dual-rail architecture improves efficiency in low-VOUT applications, as detailed in Sections 3 and 7.1.
