Pololu 3.3V, 600mA Step-Down Voltage Regulator D36V6F3 Spannungsregler

Overview

The D36V6x family of buck (step-down) voltage regulators generates lower output voltages from input voltages as high as 50 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters), which makes them much more efficient than linear voltage regulators, especially when the difference between the input and output voltage is large.

Features

• Input voltage: 4 V to 50 V (minimum input subject to dropout voltage considerations for currents over 400 mA; see the dropout voltage section for details)
• Output voltage: 3.3 V with 4% accuracy
• Maximum output current: 600 mA (see the maximum continuous output current graph below)
• Fixed 2.1 MHz switching frequency
• High-voltage enable input can put the board into a low-power state where it draws less than 2 µA (typical)
• Low quiescent current: < 0.1 mA (see the quiescent current graph below)
• Over-current and short-circuit protection, over-temperature shutoff
• Small size: 0.5? × 0.4? × 0.1? (13 mm × 10 mm × 3 mm)
• Weight: 0.5 g

Dimensions

• Size: 0.4? × 0.5? × 0.1?¹
• Weight: 0.5 g¹

General specifications

• Minimum operating voltage: 4 V²
• Maximum operating voltage: 50 V
• Maximum output current: 600 mA
• Output voltage: 3.3 V
• Reverse voltage protection?: N
• Maximum quiescent current: 0.1 mA³
• Output type: fixed 3.3V

Identifying markings

Notes:

1. Without included optional headers.

2. Subject to dropout voltage considerations.

3. While enabled with no load. Can be reduced to under 2 µA using the enable pin.
