Product details

Overview

ZXRE060H5TA from Diodes Incorporated is a 5-pin adjustable precision shunt regulator with 0.6V feedback reference voltage, ±1% initial tolerance at +25°C, -40°C to +125°C operating range, and open-collector output capable of 0.2V–18V operation-designed for isolated DC-DC converters and low-voltage point-of-load regulation in microprocessor/DSP core supplies.

For engineers reviewing the ZXRE060H5TA datasheet, ZXRE060H5TA pinout, ZXRE060H5TA application, or ZXRE060H5TA equivalent, key selection criteria include its 0.6V FB threshold, separate IN/OUT pins enabling low-dropout series LDO configurations, SC70-5 package compatibility with TL432/TLV431 footprints, and temperature-stable <12mV drift over -40°C to +125°C.

Technical Context

The ZXRE060H5TA implements a high-transconductance (5000 mA/V) amplifier with 600 kHz unity-gain bandwidth to regulate output voltage via external resistor divider on the FB pin, maintaining 0.6V nominal reference with <10 mV load/line regulation error across full temperature and current range.

Its architecture separates power ground (PGND) and analog ground (GND), isolates input supply (IN) from open-collector output (OUT), and supports opto-coupled feedback loops-enabling stable regulation of rails as low as 0.6V while operating from auxiliary supplies down to 2.2V at -40°C.

Key Specifications

Parameter	Value and Actual Design Meaning
Feedback Voltage (V_FB)	0.6 V nominal; sets regulated output via R1/R2 divider; enables 0.6V–18V adjustable rail control.
Initial Tolerance	±1% at +25°C; ensures accurate voltage setting without calibration in production POL designs.
Temp Drift (−40°C to +125°C)	<12 mV; guarantees ≤±0.02% output variation over full industrial temperature range.
Output Voltage Range	0.2 V to 18 V; supports ultra-low-voltage core rails and high-side shunt regulation in isolated topologies.
OUT Pin Current	0.3 mA to 15 mA; provides sufficient sink capability for optocoupler LED drive and series pass transistor biasing.
PSRR @ 300 kHz	>45 dB; rejects high-frequency noise from switching regulators feeding the IN pin.
Dynamic Output Impedance	0.6 Ω max (−40°C to +125°C); ensures tight regulation under dynamic load transients.

Pinout & Package

ZXRE060H5TA is packaged in SC70-5 (SOT353), a 1.25 mm × 2.1 mm, 0.95 mm height low-profile surface-mount package with gull-wing leads and thermal pad exposed on bottom (not electrically connected).

Pin	Circuit Role	Design Meaning
1 (PGND)	Power Ground	Emitter return path for output transistor; must be tied to system GND to enable proper current sinking.
2 (N/C)	No Connection	Internally unconnected; leave floating or avoid PCB trace routing to prevent parasitic coupling.
3 (OUT)	Open-Collector Output	Sinks up to 15 mA; connects to cathode of optocoupler LED or base of series pass transistor.
4 (FB)	Feedback Input	Compares against 0.6V internal reference; voltage divider from regulated rail sets output voltage.
5 (GND)	Analog Ground	Reference and amplifier ground return; must be shorted to PGND for stable bandgap operation.

Key Features

Feature	Design Value
0.6V Reference Threshold	Enables direct regulation of sub-1V microprocessor core rails without level-shifting circuitry.
Separate IN and OUT Pins	Allows IN to be powered from auxiliary rail while OUT controls master rail-enabling true low-dropout LDO behavior.
SC70-5 Footprint Compatibility	Pinout matches TL432/TLV431 SOT23-3 cathode/anode/reference mapping-simplifies drop-in upgrade in existing designs.
High PSRR (>45 dB @ 300 kHz)	Maintains regulation accuracy despite ripple on auxiliary supply feeding the IN pin in isolated converters.
−40°C to +125°C Operation	Validated performance across full industrial temperature range without derating or external compensation.

Applications

Isolated DC-DC Converters

Core Voltage POL Regulation

Use Scenario: Secondary-side voltage regulation in flyback or forward converters using optocoupler feedback loop.

IC Role / Device Role / Timing Role: Shunt reference providing precise 0.6V feedback threshold to control optocoupler LED current and thus primary-side PWM duty cycle.

Use Value: Enables stable 0.6V–1.2V output regulation with <12mV total drift, eliminating need for external voltage scaling.

Use Scenario: Point-of-load regulation for FPGA, DSP, or ASIC core supplies requiring <1V rails with tight tolerance.

IC Role / Device Role / Timing Role: Adjustable shunt reference in series-pass LDO configuration, setting output via external resistors while sinking base current.

Use Value: Achieves 0.6V minimum output with ±1% accuracy and <0.6Ω dynamic impedance-critical for dynamic core load response.

Low-Voltage Low-Dropout Linear Regulators

Adjustable Voltage Reference

Use Scenario: Low-input-voltage LDO where VIN may be only 200mV above VOUT, e.g., battery-powered sensor nodes.

IC Role / Device Role / Timing Role: Feedback element in emitter-follower or PNP-based series regulator, leveraging separate IN/OUT pins for rail independence.

Use Value: Supports dropout as low as 200mV by allowing OUT to operate down to 0.2V while IN is supplied from higher auxiliary rail.

Use Scenario: Precision reference source for ADCs, DACs, or comparators requiring stable sub-1V reference voltage.

IC Role / Device Role / Timing Role: Two-terminal shunt reference configured with fixed resistor divider to generate custom reference voltage.

Use Value: Delivers 0.6V reference with <10mV line/load regulation error-superior to standard 1.2V bandgap references in low-voltage signal chains.

Equivalent & Alternatives

The following parts are listed as comparable options for similar shunt regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV431AIDBVR	Fixed 1.24V reference; no 0.6V option; SOT23-3, 3-pin; lower temp drift (±0.5% @25°C, 39 ppm/°C).	Cannot regulate rails below 1.24V; requires external resistor divider for adjustment; unsuitable for sub-1V core supplies.	Select when 1.24V reference suffices and board space is constrained to 3-pin SOT23 footprint.
ZXRE160E5TA	0.6V reference; ±0.5% tolerance; same SC70-5 package; improved temp drift (<6mV over −40°C to +85°C).	Same functional role but tighter initial tolerance and better stability-intended as next-generation replacement.	Prefer for new designs requiring higher accuracy; ZXRE060H5TA remains valid for cost-sensitive legacy upgrades.

Compared with TLV431AIDBVR and ZXRE160E5TA, ZXRE060H5TA uniquely enables 0.6V regulation in SC70-5 with 1% tolerance and proven stability in opto-isolated 0.6V POL converters-making it optimal for cost-constrained industrial upgrades where 0.6V capability is mandatory.

FAQ

What is the minimum input voltage required for ZXRE060H5TA to regulate a 0.6V output?

The ZXRE060H5TA requires a minimum IN voltage of 2.2V at −40°C and 2.0V at 0°C to +125°C per datasheet specifications. This headroom accommodates internal amplifier operation and ensures stable 0.6V regulation even with worst-case process and temperature variation. The device cannot regulate when VIN falls below these thresholds.

Can ZXRE060H5TA replace TL432 in existing SOT23-3 designs without PCB changes?

No-ZXRE060H5TA uses SC70-5 (5-pin) packaging, while TL432 uses SOT23-3 (3-pin). However, its TSOT23-5 variant (ZXRE060ET5TA) has OUT/GND/FB pins aligned with TL432's cathode/anode/reference pins, enabling mechanical and functional replacement with minor layout revision to accommodate the extra two pins.

How does the N/C pin (Pin 2) affect PCB layout or thermal performance?

Pin 2 is internally unconnected and carries no electrical function. It must remain unconnected on the PCB-no trace, pad, or solder mask opening is required. Leaving it floating has no impact on thermal performance; the SC70-5 package's thermal dissipation is dominated by the exposed thermal pad (not present in this variant) and GND/PGND connections.

What is the maximum recommended capacitor value on the FB pin for stability?

The datasheet does not specify a maximum FB capacitor value, but recommends placing a 0.1 µF ceramic capacitor close to the device between IN and GND, and a 0.1–10 µF compensation capacitor (C2) between OUT and GND. FB pin capacitance should be minimized-typically <10 pF-to avoid phase shift that could destabilize the control loop.
