Product details
Overview
MAX8532EBTJ-T from Maxim Integrated is a low-noise, low-dropout linear regulator with 2.85V fixed 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-ideal for battery-powered portable devices requiring stable, quiet voltage rails.
For engineers reviewing the MAX8532EBTJ-T datasheet, MAX8532EBTJ-T pinout, MAX8532EBTJ-T application, or MAX8532EBTJ-T equivalent, key selection criteria include guaranteed 200mA output, ultra-low shutdown current (<1µA), 62dB PSRR at 100Hz, thermal/short-circuit protection, and UCSP package compatibility with space-constrained PCB layouts.
Technical Context
The MAX8532EBTJ-T integrates an internal 1.25V bandgap reference, error amplifier, and P-channel MOSFET pass transistor (RDS(ON) ≈ 1Ω) to achieve load-proportional dropout and near-constant 80µA supply current across operating conditions. Its BP pin enables noise reduction via external 10nF ceramic bypass capacitor.
Shutdown is controlled by a logic-level SHDN input with 0.4V VIL and 1.6V VIH, drawing only 0.01µA at +25°C when asserted. Thermal protection activates at +160°C with 10°C hysteresis, and current limiting holds output at ≥210mA minimum before foldback.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.85V ±3% over -40°C to +85°C - ensures stable core/peripheral rail for 2.8V–3.0V logic domains. |
| Max Output Current | 200mA continuous - supports moderate-power RF modules, sensors, or microcontroller subsystems. |
| Dropout Voltage | 100mV (typ) at 100mA - extends usable battery life down to ~2.95V input for 2.85V output. |
| Output Noise | 40µVRMS (10Hz–100kHz) - meets low-noise analog/RF supply requirements without additional LDO staging. |
| PSRR | 62dB at 100Hz - suppresses switching noise from adjacent DC-DC converters in mixed-signal systems. |
| Quiescent Current | 80µA (no load) - minimizes standby power loss in always-on portable applications. |
| Shutdown Current | 0.01µA at +25°C - enables multi-year battery operation in sleep-mode IoT endpoints. |
Pinout & Package
MAX8532EBTJ-T is housed in a 1.16mm × 1.57mm × 0.66mm, 6-bump UCSP (Ultra-Compact Silicon Package) with 3×2 bump grid. The package uses solder bumps instead of leads and requires compatible PCB land pattern (Maxim outline no. 21-0097).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B2 | IN | Regulator input - accepts 2.5V–6.5V; requires ≥2.2µF ceramic input capacitor for stability. |
| B1 | OUT | Regulated 2.85V output - delivers up to 200mA; requires ≥2.2µF ceramic output capacitor. |
| A1 | GND | Analog ground reference - must be connected directly to low-impedance PCB ground plane. |
| A2 | SHDN | Active-low shutdown control - logic low disables regulator; connect to IN or high for normal operation. |
| A3 | BP | Reference bypass - connects to 10nF ceramic capacitor to reduce output noise by filtering reference path. |
| B3 | N.C. | No connection - floating bump; no PCB trace or pad required. |
Key Features
| Feature | Design Value |
|---|---|
| P-channel MOSFET pass element | Enables load-proportional dropout (vs. fixed PNP saturation voltage), improving light-load efficiency and battery runtime. |
| Integrated current limit | Guarantees ≥210mA minimum current limit - protects against sustained short-circuit faults without external components. |
| Thermal shutdown with hysteresis | Activates at +160°C junction temperature and re-enables after 10°C cooldown - prevents thermal runaway during overload. |
| Low-noise BP pin architecture | External 10nF capacitor on BP reduces output noise to 40µVRMS - eliminates need for post-regulation filtering in sensitive analog stages. |
| Ultra-low shutdown current | 0.01µA at +25°C - enables deep-sleep modes in battery-powered instrumentation with multi-year shelf life. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, low-dropout linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A20285PDBVR | 2.85V fixed, 300mA output, 65dB PSRR at 1kHz, 6.5µVRMS noise - lower noise but higher cost and larger SOT-23-5 package. | Preferred where sub-10µV noise is critical (e.g., high-resolution audio codecs); less suitable for ultra-dense UCSP layouts. | Select TPS7A20285PDBVR if noise budget is <10µVRMS and board area allows SOT-23 footprint. |
| MCP1700T-2802E/TT | 2.8V fixed (±2%), 250mA output, 175mV dropout at 250mA, 85µA quiescent current - slightly higher dropout and looser accuracy than MAX8532EBTJ-T. | Suitable for cost-sensitive industrial sensors where 2.8V vs. 2.85V tolerance is acceptable and 100mV dropout margin is not required. | Select MCP1700T-2802E/TT for price-driven designs with relaxed voltage and dropout specs. |
Compared with TPS7A20285PDBVR and MCP1700T-2802E/TT, the MAX8532EBTJ-T offers the smallest footprint (UCSP), best balance of 40µVRMS noise and 100mV dropout, and lowest shutdown current - making it optimal for space- and battery-life-constrained portable electronics.

FAQ
What is the output voltage tolerance of the MAX8532EBTJ-T over temperature?
The MAX8532EBTJ-T guarantees ±3% output voltage accuracy over the full -40°C to +85°C operating temperature range at load currents from 0.1mA to 200mA. At +25°C and 1mA load, the tolerance tightens to ±1%. This specification ensures reliable operation of 2.85V-dependent logic and analog circuits across environmental extremes without external trimming.
Does the MAX8532EBTJ-T require external capacitors, and what values are recommended?
Yes, the MAX8532EBTJ-T requires external capacitors for stability and performance. A minimum 2.2µF ceramic capacitor is required on the OUT pin (X7R/X5R dielectric preferred), and a 2.2µF ceramic capacitor is recommended on IN. For lowest noise, a 10nF ceramic capacitor must be placed on the BP pin. Using smaller or non-ceramic capacitors may cause instability or increased output ripple.
How does the MAX8532EBTJ-T behave during thermal overload?
When the MAX8532EBTJ-T junction temperature exceeds +160°C, its internal thermal sensor triggers shutdown, turning off the pass transistor. After the die cools by 10°C (to ~150°C), the regulator automatically resumes operation. This hysteresis prevents rapid cycling and provides pulsed output during sustained overload - protecting the device while allowing recovery once ambient conditions improve.
Can the MAX8532EBTJ-T be used with input voltages below 2.5V?
No, the MAX8532EBTJ-T has a specified minimum input voltage of 2.5V per its Absolute Maximum Ratings and Electrical Characteristics tables. Operation below 2.5V may result in undervoltage lockout (UVLO) activation at ~2.2V (with 40mV hysteresis) or unregulated output. For sub-2.5V inputs, consider alternative regulators such as the MAX8526 series designed for 1.6V–3.6V operation.
Is the MAX8532EBTJ-T pin-compatible with other variants in the MAX8532 family?
Yes, all MAX8532 variants-including MAX8532EBTG (3.0V), MAX8532EBT2 (1.8V), and MAX8532EBTJ-T (2.85V)-share identical 6-pin UCSP packaging, pinout, and electrical interface. Only the output voltage and top-mark code differ; no PCB layout changes are needed when substituting between these variants for voltage-scaling design iterations.
