Product details
Overview
UPC2910HB-AZ from Renesas Electronics is a 10 V, 1 A low-dropout linear voltage regulator using a PNP output transistor in SC-64 (MP-3) package. It delivers stable output with 0.7 V typical dropout at 1 A, integrated over-current and thermal shutdown protection, and supports industrial ambient temperatures from –30°C to +85°C. It is used in embedded power rails for microcontrollers and analog circuitry requiring clean, regulated 10 V supply.
For engineers reviewing the UPC2910HB-AZ datasheet, UPC2910HB-AZ pinout, UPC2910HB-AZ application, or UPC2910HB-AZ equivalent, key selection criteria include dropout voltage at full load, thermal resistance (12.5°C/W junction-to-case), quiescent current behavior across input voltage range, and compatibility with low-ESR output capacitors for stability in space-constrained designs.
Technical Context
The UPC2910HB-AZ implements a PNP-based LDO architecture with internal reference voltage, error amplifier, drive circuit, and multiple protection blocks-including safe operating area (SOA) limiting, thermal shutdown triggered above 150°C junction temperature, and foldback over-current protection. Its regulation loop maintains output accuracy under varying line (11–18 V input) and load (0–1 A) conditions.
Unlike NPN-based regulators, the PNP topology enables lower dropout and reduced power dissipation at high output currents. The device requires external 0.1 µF input and ≥47 µF output capacitors-low-impedance electrolytic recommended for sub-zero operation-and includes dedicated GND pins (Pin 2 and Pin 4 fin) tied internally for enhanced thermal and noise performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 10.0 V ±5% (9.5–10.5 V over full temp/load range); meets tight tolerance requirements for analog sensor biasing and ADC reference rails. |
| Dropout Voltage | 0.7 V typical at 1 A (max 1.0 V); enables operation with only 11 V input, critical for battery-backed or low-headroom systems. |
| Output Current | 1.0 A continuous; supports powering multiple ICs or small peripheral modules without external pass devices. |
| Quiescent Current | 2.0–25 mA (0–1 A load); low no-load draw extends standby time in always-on subsystems. |
| Thermal Resistance | 12.5°C/W (junction-to-case); allows direct mounting to PCB copper pour or small heatsink for sustained 1 A operation at +85°C ambient. |
| Ripple Rejection | 40–56 dB (120 Hz, 11–18 V input); suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Noise Voltage | 180 µVr.m.s. (10 Hz–100 kHz); suitable for low-noise analog signal chains where PSRR alone is insufficient. |
Pinout & Package
UPC2910HB-AZ uses the SC-64 (MP-3) surface-mount package - a 4-pin, isolated plastic case with exposed metal fin (Pin 4) serving as GND and thermal path. Pins are arranged in single-row configuration with 2.54 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | INPUT | Unregulated positive input (11–18 V); must be decoupled with ≥0.1 µF capacitor placed within 1–2 cm to prevent oscillation. |
| 2 | GND | Signal ground reference; electrically common with Pin 4 fin but routed separately on PCB for noise isolation. |
| 3 | OUTPUT | Regulated 10 V output; requires ≥47 µF low-ESR electrolytic capacitor near pin for transient response and stability. |
| 4 | GND (Fin) | Exposed metal thermal pad tied to internal GND; must be soldered to large PCB copper area for effective heat dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout operation | 0.7 V typical at 1 A enables use in 12 V systems with minimal headroom loss and reduced thermal stress vs. standard 78xx regulators. |
| Integrated SOA protection | Prevents destructive second breakdown during short-circuit or high-VIN/IO transients without external current-sense components. |
| Dual-GND configuration | Separate signal GND (Pin 2) and thermal GND (Pin 4 fin) minimizes ground bounce and improves PSRR in mixed-signal layouts. |
| Pb-free construction | AZ suffix confirms RoHS-compliant Sn-plated external electrodes with no lead content-verified per JEDEC J-STD-609. |
| Wide input voltage range | Supports 11–18 V input, accommodating automotive battery variations (cold crank, load dump) when paired with front-end protection. |
Applications
| Industrial PLC I/O Module | Medical Patient Monitor Analog Front-End |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1117-10CPK | 10 V fixed-output, 800 mA, 1.2 V dropout (NPN), SOT-223 package, higher quiescent current (5–10 mA). | Limited to 800 mA; unsuitable for 1 A continuous loads without derating or parallel configuration. | Select when board space is constrained and 800 mA suffices; verify thermal margin with 62°C/W junction-to-ambient. |
| LD1086DT10TR | 10 V fixed-output, 1.5 A, 1.5 V dropout (NPN), TO-263 package, wider input range (2.5–30 V). | Higher dropout increases power loss at low VIN; larger TO-263 footprint requires more PCB area than SC-64. | Choose for higher current headroom or wider input flexibility; accept 1.5 V dropout penalty in 12 V systems. |
Compared with TLV1117-10CPK and LD1086DT10TR, UPC2910HB-AZ provides the lowest dropout (0.7 V) in a compact SC-64 package while delivering full 1 A, making it optimal for thermally sensitive, low-headroom 10 V rail designs where efficiency and size are prioritized over ultra-wide input range.

FAQ
What is the maximum input voltage rating for the UPC2910HB-AZ?
The UPC2910HB-AZ has an absolute maximum input voltage rating of 20 V. Operation must remain within the recommended input range of 11–18 V to ensure specified performance and reliability. Exceeding 20 V-even momentarily-may cause permanent damage due to internal junction breakdown, as confirmed in the Absolute Maximum Ratings table of Renesas Data Sheet G10026EJ4V0DS.
Does the UPC2910HB-AZ require external capacitors, and what values are recommended?
Yes, the UPC2910HB-AZ requires both input and output capacitors for stability. A minimum 0.1 µF ceramic capacitor must be placed within 1–2 cm of the INPUT pin to suppress parasitic oscillation. A minimum 47 µF low-impedance electrolytic capacitor is required at the OUTPUT pin to ensure load regulation and transient response. Renesas specifies these values in the Typical Connection diagram and cautions against omitting either capacitor.
How does the dual-GND configuration (Pin 2 and Pin 4) function in the UPC2910HB-AZ?
In the UPC2910HB-AZ, Pin 2 is the signal ground terminal and Pin 4 is the exposed metal fin tied internally to GND for thermal conduction. Though electrically common, they serve distinct roles: Pin 2 carries return current for regulation feedback, while Pin 4 provides a low-thermal-resistance path to PCB copper. This separation reduces ground noise coupling into the error amplifier, improving PSRR and output stability in mixed-signal layouts.
What protection features are integrated into the UPC2910HB-AZ?
The UPC2910HB-AZ integrates four protection functions: (1) Over-current protection with foldback limiting, (2) Thermal shutdown activating above 150°C junction temperature, (3) Safe operating area (SOA) protection preventing second breakdown during high-stress transients, and (4) Internal saturation protection in the drive circuit. These are implemented entirely on-die and require no external components, as detailed in the Block Diagram and Features section of the datasheet.
Is the UPC2910HB-AZ compatible with lead-free reflow processes?
Yes, the UPC2910HB-AZ is Pb-free compliant (AZ suffix) and qualified for lead-free reflow soldering per IR60-00-3 profile: peak package surface temperature ≤260°C, duration ≥220°C for ≤60 seconds, with up to three reflow cycles. This is explicitly defined in the Recommended Soldering Conditions section of Renesas Data Sheet G10026EJ4V0DS, distinguishing it from non-AZ variants.
