500mV over all operating conditions allows the GL39500 series to provide 2.5V from a supply as low as 3V or 1.8V. The GL39500 series also has fast transient response, for heavy switching applications. The device requires only 47 uF of output capacitance to maintain stability and achieve fast transient response. The GL39500 series is fully protected with over current limiting, thermal shutdown, reversed-battery protection, reversed-lead insertion protection, and reversed-leakage protection. The GL39501 ser
ies offers a TTL-logic-compatible enable pin and an error flag that indicates under voltage and over current conditions. Offered in a fixed voltage, 1.8V and 2.5V, the GL39500 series comes in the TO-220 and TO-263 packages and is an ideal upgrade to older, NPN-based linear voltage regulators. |

GL6250 |
| Description |
GL6250 combine high accuracy with very low power consumption, and provides high output current even when the application requires extremely low input-output voltage differential.
GL6250 includes a precision voltage reference, an error correction circuit, over-temperature protection, and a current limited output driver. Fast transient response to load variations provides excellent stability under dynamic load conditions.
GL6250 comes in SOT-23 (150mW) and TO-92 packages. |
| Features: |
| - Maximum output current 250mA (within maximum power dissipation) |
| - Output voltage: from 1.8 V to 5.0V in 0.1V increments |
| - Output voltage 2% |
| - CMOS low power consumption, typically 1.0A at Vout = 5.0V |
| - Input stability typically 0.2%/V |
| - Ultra-low dropout voltage 0.38V @ Iout = 200mA at Vout = 5.0V |
| - Small input/ output differential: 0.4V at 160mA (Vout = 3.3V) |
| - SOT-23 (150mW) and TO-92 packages |
