Overview
LM337 Three-terminal adjustable negative voltage regulators TO-220 Datasheet - production data current limit, thermal overload protection and safe area protection.
All overload protection circuitry remains fully functional even if the adjustment terminal is disconnected.
Table 1.
Device summary Order codes Packages Temperature range LM337SP TO-220 0 °C to 125 °C Features • Output voltage adjustable down to VREF • 1.
5 A guaranteed output current • 0.
3%/V typical load regulation • 0.
01%/V typical line regulation • Current limit constant with temperature • Ripple rejection: 77 dB • Standard 3-lead transistor packages • Excellent thermal regulation: 0.
002%/V • 50 ppm/°C temperature coefficient Description The LM337 series are adjustable 3-terminal negative voltage regulators capable of supplying in excess -1.
5 A over a -1.
2 to -37 V output voltage range.
They are exceptionally easy to use and require only two external resistors to set the output voltage.
Further, both line and load regulation are better than standard fixed regulators.
Also, LM337 regulators are supplied in standard transistor packages which are easily mounted and handled.
In addition to higher performance than fixed regulators, the LM337 series offer full overload protection available only in integrated circuits.
