Product details
Overview
MAX8532EBT2 from Maxim Integrated is a low-noise, low-dropout linear regulator with fixed 1.8V output, delivering up to 200mA from 2.5V–6.5V input. It features 100mV typical dropout at 100mA, 40µVRMS output noise, and 80µA quiescent current-designed for space-constrained portable power rails in digital cameras and handheld instruments.
For engineers reviewing the MAX8532EBT2 datasheet, MAX8532EBT2 pinout, MAX8532EBT2 application, or MAX8532EBT2 equivalent, key selection criteria include guaranteed 200mA output, UCSP package footprint (1.16mm × 1.57mm), thermal-shutdown protection, and BP-pin noise-bypass capability for ultra-low-noise analog supply domains.
Technical Context
The MAX8532EBT2 integrates a P-channel MOSFET pass transistor with 1Ω RDS(ON), enabling load-proportional dropout voltage and eliminating base-drive current losses typical of PNP-based LDOs. Its internal 1.25V bandgap reference feeds an error amplifier that controls the pass gate via feedback from the internal resistor divider tied to OUT.
Shutdown is implemented via a logic-level SHDN pin with <1µA off-state current; the BP pin connects to an internal RC filter for noise reduction when bypassed with 10nF. Thermal protection activates at +160°C with 10°C hysteresis, and current limiting holds output at ≥210mA min under overload.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8V ±3% over -40°C to +85°C - ensures stable core voltage for 1.8V I/O or low-power microcontrollers. |
| Max Output Current | 200mA continuous - sufficient for powering RF transceivers or sensor signal chains without external boost. |
| Dropout Voltage | 100mV (typ) at 100mA - enables operation down to 1.9V input, extending battery life in single-cell Li-ion or Li-poly systems. |
| Output Noise | 40µVRMS (10Hz–100kHz) with 10nF BP cap - meets low-noise requirements for ADC references or RF VCO supplies. |
| PSRR | 62dB at 100Hz - suppresses ripple from noisy DC-DC converters feeding the LDO input. |
| Quiescent Current | 80µA (no load) - minimizes standby drain in always-on sensor nodes or real-time clock domains. |
| Shutdown Current | 0.01µA (typ) at +25°C - supports deep-sleep modes with sub-100nA system leakage budgets. |
Pinout & Package
MAX8532EBT2 is housed in a 6-pin Ultra-Thin Chip Scale Package (UCSP) measuring 1.16mm × 1.57mm × 0.66mm with 3×2 bump array. The package uses face-down flip-chip mounting and requires RoHS-compliant reflow profile (peak 260°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B3 | N.C. | No internal connection - must be left floating or grounded per PCB layout best practices; no routing required. |
| B2 | IN | Main power input (2.5V–6.5V); requires ≥2.2µF ceramic capacitor close to pin for stability and line transient suppression. |
| B1 | OUT | Regulated 1.8V output; capable of sourcing 200mA; requires ≥2.2µF ceramic output capacitor for load transient response. |
| A1 | GND | Analog ground reference; must connect directly to low-impedance ground plane to minimize noise coupling into BP and error amp. |
| A2 | SHDN | Active-low enable; pulled high to IN for normal operation; driven low to reduce IQ to <1µA - enables system-level power sequencing. |
| A3 | BP | Reference bypass node; requires 10nF ceramic capacitor to GND to reduce output noise by filtering internal reference ripple. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise regulation | 40µVRMS output noise with 10nF BP cap - enables clean power for precision analog circuits without additional filtering stages. |
| P-channel pass transistor | 1Ω RDS(ON) eliminates base-drive current loss - maintains 80µA IQ across full load and dropout range, unlike PNP LDOs. |
| Thermal shutdown with hysteresis | Activates at +160°C, resets at +150°C - provides self-recovering fault protection during sustained overload or poor heatsinking. |
| Internal current limit | 210mA minimum trip threshold - allows indefinite short-circuit survival while preventing damage during board-level test or ESD events. |
| Ultra-small UCSP footprint | 1.16mm × 1.57mm area - fits within tight spacing constraints of PCMCIA cards and wireless LAN modules where board area is premium. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, low-dropout LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A0518PDBVR | 1.8V fixed, 200mA, 170mV dropout at 100mA, SOT-23-5 package (2.9mm × 1.6mm) | Larger footprint; higher dropout reduces battery end-of-life margin in single-cell systems | Select when board space permits larger package and lower cost is prioritized over minimal dropout. |
| MCP1700T-1802E/TT | 1.8V fixed, 250mA, 175mV dropout at 100mA, SOT-23-3 package; no BP pin or adjustable noise filtering | No reference bypass capability - output noise ~120µVRMS limits use in precision analog rails | Select for cost-sensitive, non-noise-critical digital rails where BP functionality is unnecessary. |
Compared with TPS7A0518PDBVR and MCP1700T-1802E/TT, the MAX8532EBT2 delivers superior dropout performance and integrated noise reduction via the BP pin-critical for battery-powered analog-intensive applications where board area and power efficiency are constrained.

FAQ
What is the output voltage tolerance of the MAX8532EBT2 over temperature and load?
The MAX8532EBT2 guarantees ±3% output voltage accuracy across the full operating temperature range (-40°C to +85°C) and load current range (0.1mA to 200mA). At +25°C and 1mA load, the tolerance tightens to ±1%. This specification ensures reliable operation of 1.8V logic interfaces without external trimming or calibration in consumer portable devices.
Does the MAX8532EBT2 require an external capacitor on the BP pin, and what value is recommended?
Yes, the MAX8532EBT2 requires a 10nF ceramic capacitor between the BP pin and GND to achieve its specified 40µVRMS output noise. This capacitor forms a low-pass filter with an internal resistor to suppress reference voltage ripple. Using values significantly outside 10nF degrades noise performance and may impact regulation stability under dynamic load conditions.
Can the MAX8532EBT2 operate with input voltages below 2.5V?
No, the MAX8532EBT2 has a minimum input voltage of 2.5V per its Absolute Maximum Ratings and Electrical Characteristics tables. Operation below this threshold risks undervoltage lockout activation (VUVLO = 2.25V typ) and unregulated output. For sub-2.5V inputs, alternative regulators such as the MAX1725 or TPS7A02 series should be evaluated.
What is the thermal shutdown behavior of the MAX8532EBT2 during continuous overload?
The MAX8532EBT2 activates thermal shutdown at +160°C junction temperature and remains off until the die cools by 10°C (to +150°C), then automatically resumes regulation. Under continuous overload, this results in pulsed output rather than latch-off, allowing safe evaluation of thermal design margins without manual reset intervention.
Is the MAX8532EBT2 pin-compatible with other variants in the MAX8532 family, such as MAX8532EBTG or MAX8532EBTJ?
Yes, all MAX8532 variants-including MAX8532EBT2, MAX8532EBTG (3.0V), and MAX8532EBTJ (2.85V)-share identical UCSP-6 packaging, pinout, and electrical interface. Only the output voltage and top-mark code differ; no PCB redesign is needed when substituting between these variants for different voltage rail requirements.
