The Leader in High Temperature Semiconductor Solutions CHT-BG3M-Datasheet Version: 1.7 27-Nov-14 (Last Modification Date) High Temperature Voltage Reference 2.5V; 3.3V; 5V; 9V; 10V or 12V +/- 2% General Description Features The CHT-BG3M is a bandgap voltage reference compatible with High Temperature environments. Typical operation temperature range extends from -55C to 225C. Its total precision (initial plus temperature drift plus line and load regulation) is better than 2%. The CHT-BG3M has a quiescent current consumption of 700A. The circuit can deliver an output current of up to 3mA into an external load at 225C. It is stable throughout the whole temperature range for load capacitances between 0 and 3nF.

Other packages (1) The minimum dropout voltage is 1.5V with a load current lower than 1mA and (1) 2.5V at 3mA load current. The maximum acceptable dropout voltage (Vin-Vout) is 15V. The CHT-BG3M is available in TO-39 package and in bare die. Other packages are available upon request. available on request. Validated at 225C for 30000 hours (and still on-going) Start-up operational over the whole temperature range Latch-up free Applications Precise Voltage reference with low temperature drift for High Temperature electronic systems used in Well logging, Automotive, Aeronautics or Aerospace applications. Note 1: for CHT-BG3M-025, min dropout is 2V @1mA and 3V @3mA Note 2: Input voltage cannot exceed 25V. PUBLIC Doc.

This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Frequent or extended exposure to absolute maximum rating conditions or above may affect device reliability. During power up/restart without voltage regulator and depending on the quality of the power supply, peak voltage higher than 25V may be seen by the BG3M input, which exceeds the absolute maximum ratings and can cause permanent damage. This issue can be minimized by adding big decoupling capacitor (>10F) close to the BG3M input. Electrical Characteristics Following table is relative to the 5V mode (CHT-BG3M-050).
